Silicon carbide has two similar crystalline forms, which are both related to the diamond structure. Boron carbide (B 4 C), on the other hand, has an unusual structure that includes icosahedral boron units linked by carbon atoms. In this respect, boron carbide is
Sand or silicon dioxide, SiO2, racts with carbon to form silicon carbine, SiC, and carbon monoxide CO. When 100 kg of sand is treated in this way 51.4 kg of SiC are recovered. What is the percent yield of silicon carbide? I don''t understand if this is a coustion
Silicon dies which are placed on a wafer can also be described as many squares placed inside a circle — thus the calculation is about first finding the overall circle area using both the mathematical nuer Pi (approximately equal to 3.14159) and the wafer size.

The properties of silicon carbide are highly dependent on its crystal structure (it can exist in many polytypes), on the quality of the crystal, and on the nuer and types of defects present. Manufacturers of silicon carbide raw material and devices need to monitor and control these attributes to enhance yield.
