INTRODUCTION Silicon carbide (SiC) is produced by mixing quartz sand and petrol coke in an electric resistance furnace (Smoak et al., 1978).Small-scale production of SiC was started by Edward Goodrich Acheson in the 1891 and has risen steadily since then (Smoak et al., 1978).).
Highly disperse silicon carbide is synthesized using a hybrid method comprising the sol-gel step to provide the SiO2-C starting mixture involving the formation of a transparent gel and carbothermal synthesis under relatively soft conditions, namely, at temperatures of 1200–1500°C under a dynamic vacuum. The elemental and phase compositions of the products and their thermal behavior in air

Moreover, we will cover various appliions
Silicon carbide has been the most widely used material for the use of structural ceramics. Characteristics such as relatively low thermal expansion, high force-to-weight radius, high thermal conductivity, hardness, resistance to abrasion and corrosion, and most importantly, the maintenance of elastic resistance at temperatures up to 1650 ° C, have led to a wide range of uses.
