Silicon dioxide calcium plates are classified as a type of ceramic material. Ceramic materials are non-metallic, inorganic compounds that are typically made by heating and cooling a mixture of clay and other minerals. Silicon dioxide, also known as silica, is a common component of ceramic materials due to its abundance in nature and its high melting point. Calcium plates, on the other hand, are typically made from calcium-based compounds such as calcium carbonate or calcium oxide. These...
After the titanium dioxide large sizes are calcined aggregate and sinter, it must be pulverized to a size of the original pigment substantially (about 0.15 0.35μm ~), in order to fully reflect its optical properties and pigment properties. The basic pigment particles are primary primary particles produced during hydrolysis, and gradually grow into basic pigment particles during calcination, and then sintered together at a high temperature. The pulverization process only breaks up the aggregates...
The calcium silicate board has light weight, high strength, moisture proof, anti-corrosion and fireproof. Another remarkable feature is that it is easy to re-process, and it is not easy to be powdered and broken like the gypsum board. As a gypsum material, the calcium silicate board retains the appearance of the gypsum board in appearance compared with the gypsum board; the weight is much lower than that of the gypsum board, and the strength is much higher than that of the gypsum board; The...
Refractive index: When light is incident from one medium to another, it sometimes changes direction due to changes in speed. This phenomenon is called refraction. When light is refracted from a vacuum into a medium, the angle of incidence The ratio of the sine of the angle of refraction is called the refractive index, and the refractive index is also called the optical index. Whiteness: Whiteness is the ratio of the absorption and reflection of a substance to visible light. Relative whiteness...
Amorphous silicon solar cells are new thin film solar cells that appeared in 1976. They are completely different from single crystal silicon and polycrystalline silicon solar cells. The process is greatly simplified, silicon materials are consumed less, and power consumption is lower. The advantage is that it can generate electricity in low light conditions. However, the main problem of amorphous silicon solar cells is that the photoelectric conversion efficiency is low. At present, the...
(1) What is silicon fertilizer? Silicon fertilizer is a kind of mineral fertilizer mainly containing calcium silicate.

The appearance of the silicon fertilizer is white, taupe or black powder depending on the raw materials. It has the characteristics of non-toxic, odorless, non-corrosive, non-deteriorating and not easy to lose. The density of...
The photoelectric conversion efficiency of single crystal silicon solar cells is about 15%, and the highest is 24%. This is the highest photoelectric conversion efficiency among all kinds of solar cells, but the production cost is so large that it cannot be widely used. Commonly used. Since monocrystalline silicon is generally encapsulated with tempered glass and waterproof resin, it is durable and has a service life of up to 15 years and up to 25 years. Silicon dioxide calcium plates are...
Organic Fermentation Method Human, animal manure, crop straw, weed stems and leaves, etc. produce CO2 gas during fermentation, which is simple and easy, and low in cost, but the amount of CO2 released is not easy to adjust and control, and it is difficult to meet the required concentration requirements.
