Transformation of β-SiC from Charcoal, Coal, and Petroleum ...
2100 C to 2450 C. The transformation to a-SiC was greatly influenced by the original carbon source. Charcoal-converted b-SiC particles easily transformed to a-SiC at 2100 C, compared with b-SiC produced from coal and petroleum coke. Moreover, the amount of elemental Si in SiC particles enhanced the transformation to a-SiC at 2100 C.
Different Types of Coal - Difference Between
Bituminous Coal – This coal is dark and hard. This coal is formed when a sub bituminous coal undergoes a higher level of organic metamorphism. The carbon density of this coal is higher and accounts nearly 77 to 87 percent in a dry ash free basis; it is further divided into low volatile, high volatile and medium volatile types.

Coal - Wikipedia
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
