Production Method of Calcium Silicide CaSi2 Powder：

Raw material preparation

Calcium silicides are mainly calcium and silicon compounds. Among them, the source of calcium can be limestone, calcium oxide, calcium hydroxide, etc., and the start of silicon can be silicon dioxide, silicate minerals, etc. When preparing raw materials, calcium, and silicon compounds need to be mixed proportionally and fully ground to uniform to ensure the quality of the calcium silicide products produced.

High-temperature synthesis

High-temperature synthesis is a critical step in the production of calcium silicide. The mixture of calcium and silicon compounds is put into a high-temperature furnace and reacts at temperatures above 1000 ° C. At high temperatures, calcium and silicon compounds react chemically to form calcium silicide. This process requires control of temperature and reaction time to ensure that the resulting calcium silicide product is of excellent quality.

Cooling and grinding

After the high-temperature synthesis reaction, the resulting calcium silicide is cooled and ground to the desired fineness. This step requires professional cooling and grinding equipment to ensure that the quality and particle size distribution of calcium silicide products meet the requirements.

Packaging and storage

Pack the ground calcium silicide product and store it in a dry, cool place. When packing, pay attention to moisture, dust, and other impurities to prevent the consequences. The quality and particle size distribution of the product need to be checked regularly during storage.

Recycle and dispose of waste

The production process will produce waste, such as an incomplete reaction of calcium and silicon compounds. This waste must be recycled and disposed of to avoid polluting the environment. The recycled waste can be reused to produce calcium silicide or for other purposes.

Control of production process conditions

The control of production process conditions is an essential link in the production of calcium silicide. In the production process, it is necessary to control the ratio of raw materials, high-temperature synthesis temperature and time, cooling and grinding process parameters, etc., to ensure that the produced calcium silicide products have excellent quality and particle size distribution. At the same time, it is also necessary to pay attention to safety issues in the production process, such as avoiding high-temperature burns, corrosion, and other dangerous situations.
