Silicon Briquette 70-85%

High Purity Silicon Briquette 70-85% is a type of silicon briquette. Compared with traditional silicon briquette, it has a higher silicon content. Silicon Briquette 70 75 80 85 is the model with the highest silicon content currently produced. The raw material of ordinary Si briquette is silicon slag. This raw material is a by-product of the production of metallic silicon. And high purity si briquette uses high content of raw materials.

Silicon Briquette 70 75 80 85 These models use raw materials that containing higher levels of Metallic silicon. Therefore, not only do they have a higher Si content in the value, but their actual effect is also better. Better than ordinary low grade silicon briquette and silicon slag. 70-85% of the raw materials used to make si briquette include silicon metal slag, silicon slurry , silicon metal powder, etc. Si metal slag need to be ensure that the Si content is above 80%. Silicon slurry generally contains a high silicon content, which can reach 90%-95%, but the water content is extremely high and needs to be dried or dried. Silicon metal powder comes from the processing course of silicon, with different sizes and grade. These raw materials will be mix in different proportions.

Strength is another key factor affecting the use of silicon briquette. During use, silicon reacts with oxygen in liquid iron to form silicon dioxide, which is a deoxidation process. The silica then combines with other impurities to create scum that floats on the surface of liquid iron or liquid steel. At the same time, Si reacts with oxygen and releases a large amount of heat. For steel companies, this can significantly save energy costs. In the foundry industry, the carbon element in silicon briquette can melts into molten iron to promote the formation of graphite and improve the strength of casting products. To sum up, the strong and dense briquette can make the deoxidation and slagging process more complete and efficient. These high purity silicon briquettes require the use of special adhesives to avoid oxidation reactions between the silicon metal and the adhesive, thereby reducing the purity of silicon.
