Accurat silicon carbide content for just your need. Good for fire-resistant, abrasive and metallurgy etc. Competitive price

The material formed in the Acheson furnace varies in purity, according to its distance from the graphite resistor heat source. Colorless, pale yellow and green crystals have the highest purity and are found closest to the resistor. The color changes to blue and black at greater distance from the resistor, and these darker crystals are less pure. Nitrogen and aluminium are common impurities, and they affect the electrical conductivity of SiC.

For the time bejing, we supply the silicon carbide for the metallurgy, granule in ton bag.
