First, in the process of ceramic firing, silica is an indispensable material. In the kiln of ceramic billets and porcelain tyres, silica helps to shape and calibrate them. When ceramics are fired, they participate in many physical and chemical changes. An appropriate amount of silica can make the billet have a suitable viscosity and thermal stability under high temperature, without excessive melting or deformation. The ancient kiln utensils, exquisite and delicate, all rely on the delicate tone of silica in the formula of the billet. For example, the porcelain of Jingdezhen, Jiangxi Province, has a warm texture and firm tyre, and silica is indispensable.
Second, the production of glass is also made of silica as the main material. Although "Tiangong Kaiwu" does not specify the production of glass, it is inferred from today's reasons that silica is melted in glass and is the basic component. When melted at high temperature, silica forms the skeleton structure of glass, giving glass the characteristics of transparency, hardness and chemical stability. Ancient glazed products, although the process may be different from today, but silica is the foundation, making it shiny and durable.
Furthermore, in the field of refractory materials, silica is also important. In ancient times, metallurgy, ore refining and other industries required refractories to withstand high temperatures. Refractories containing silica can withstand extremely high temperatures and provide a stable environment for the smelting process. It is used in furnace linings, crucibles, etc., all of which have the ability to protect and support, ensuring the smooth implementation of smelting operations.
In summary, silica is a key element in ceramics, glass, refractory materials and other processes, and plays a crucial role in the development and inheritance of ancient techniques.
The first to bear the brunt is related to the air. If silica is produced or processed, its fine particles escape in the air, and if inhaled, it will easily damage the respiratory system. Gu Yun: "Qi is the life of man." The quality of air is related to life. This fine particle, accumulated in the lungs for a long time, can cause lung diseases, such as silicosis, which makes it difficult for people to breathe and their physical strength gradually decays.
Furthermore, look at water. If silica enters the water body, it may cause changes in the water quality. Although it dissolves little in water, it is dumped in large quantities, which may affect the ecology of the water body. Aquatic organisms depend on water to live, and differences in water quality may threaten the survival of organisms. Aquatic plants may be blocked by photosynthesis, and aquatic animals may be trapped in foraging and reproduction due to it.
As for soil, the increase or decrease of silica also has an impact. When appropriate, it can provide minerals for soil to help plants grow. However, excessive accumulation may cause soil compaction and poor ventilation and water permeability. Plant roots, such as human meridians, need to travel smoothly. Soil compaction makes it difficult for roots to stretch and breathe, and plant growth must be restricted by it.
The production process of silicon dioxide often requires energy and relies more on fossil fuels. This indirectly causes greenhouse gas emissions and changes the global climate. " The gas of heaven and earth is more precious than neutralization. "The increase of greenhouse gases breaks the balance of climate, and the uneven disaster of extreme cold, extreme heat, drought and flood gradually arises.
Therefore, silica is involved in the environment, from air to water, soil, and climate. Its impact is profound and extensive, and it cannot be ignored. It should be handled with caution to ensure the safety of the environment and the balance of ecology.
In terms of its hardness, it is solid and often wear-resistant. With its hardness, it can be used as a grinding tool, and it is essential for the repair and grinding of utensils. Its melting speed is high, and if you want to make it melt, you need a huge amount of money. This property makes it in a high-quality environment and can maintain its shape. Therefore, in smelting, pottery, etc., it can be used as a refractory material, and the equipment cannot be burnt.
Furthermore, the chemical properties of silicon dioxy are low. It is often difficult for other things to melt, and it can resist a variety of chemical invasions. It is because of the many uses of the chemical device and the hidden device, and it can be used to dissolve the contents, regardless of the wall.
And silicon dioxide is also a wonderful element in light. Its light transmittance is good, especially for light, which is transparent like a material. It is an indispensable material for optical devices, such as transparent and transparent materials. Light can be refracted and reflected, which can create wonders like magic scenes, help the people to create wonders, and also enable the craftsman to create the color of illusion light.
And because of its performance, it can flow through. In the field of the child, it is used as a barrier material and a circuit component to prevent it from being damaged by the flow. It can ensure the smoothness of the device, and the efficiency is not low. Where this is the case, silicon dioxide, with its unique properties, has great contributions to all kinds of things, which is a wonderful thing in heaven and earth.
Silica is chemically stable. Under normal temperature and pressure, it rarely reacts with water and acids (except hydrofluoric acid). Hydrofluoric acid can be etched because hydrofluoric acid and silica can produce silicon tetrafluoride gas and water. This reaction is specific and is often used as a method for etching glass.
When encountering a strong alkali, silica can react with it to form silicate and water. For example, it reacts with sodium hydroxide to obtain sodium silicate and water. This reaction is commonly used in industrial preparation of silicate substances.
Under high temperature conditions, silicon dioxide can react with carbon to form silicon and carbon monoxide, which is an important step in industrial silicon refining.
The chemical properties of silicon dioxide are stable, making it visible everywhere. In the field of construction, the main component of sand and gravel is silicon dioxide, which is strong and durable; in the electronics industry, silicon wafers are the core components, and the preparation of silicon wafers is mostly made of ore containing silicon dioxide. In the field of optics, glass made of silicon dioxide has good light transmittance and is widely used in lenses, optical instruments, etc.
It can be seen from the above that silicon dioxide has important uses in various fields due to its unique chemical properties, and is actually an indispensable substance in the world.
One is moisture resistance. Although silica is relatively stable, it is easy to disturb the damp gas. If stored in a damp place, or when transported on a rainy day without good protection, the moisture will gradually soak. When moisture meets silica, it may cause changes in its properties, and when used later, it may cause obstacles. Therefore, it must be stored in a dry place, and the carrier should be tightly closed during transportation to avoid contact with water vapor.
The second is to avoid impurities. Pure silica is better. If it is mixed with all kinds of impurities during storage and transportation, it will damage its quality. Sundries or substances containing other chemicals, come into contact with them, or react, destroying their original properties. If the reservoir is unclean, there are residues in it, or when transported, there are foreign substances next to it that emit particles, it can be entered into the silica. Therefore, the reservoir must be clean, and it should be kept alone when transported. Do not transport with sundries.
Third, stable temperature. Changes in temperature also affect silica. If it is overheated, its molecules may move and be uneasy, and if it is too cold, it may cause its brittle and hard state to change. If stored in a hot place, there is no way to cool down, or if it passes through a hot topic during transportation, the internal structure of silica may change. In cold times, the opposite is true, so the temperature of storage and transportation should be kept in a suitable area and should not be suddenly changed.
These three should be carefully stored and transported when storing and transporting silica. Only by keeping this number can the quality of silica be preserved for future use.
