Silicon carbide (SiC) has become an important abrasive because of its great hardness, but its application range is more than the general abrasive. For example, its high temperature resistance and thermal conductivity have become one of the preferred kiln materials for tunnel kiln or shuttle kiln, and its electrical conductivity has made it an important electric heating element. The preparation of SiC products must first prepare SiC smelting block [or: SiC particles, because it contains C and super hard, so SiC particles used to be called: emery.

But note: It is different in composition from natural emery (garnet). In industrial production, SiC smelting block is usually quartz, petroleum coke and other raw materials, auxiliary recovery materials, spent materials, through grinding and other processes to become a reasonable ratio and appropriate particle size of the charge (in order to adjust the permeability of the charge need to add an appropriate amount of wood chips, the preparation of green silicon carbide also add an appropriate amount of salt) by high temperature preparation.

The thermal equipment for preparing SiC smelting block at high temperature is a special silicon carbide electric furnace, whose structure consists of the bottom of the furnace, an end wall with electrodes on the inner surface, a detachable side wall, and a furnace core body (all called: The electric heating body in the center of the electric furnace is generally composed of graphite powder or petroleum coke installed in the center of the charge according to a certain shape and size, generally circular or rectangular. Both ends of the furnace are connected with electrodes. The firing method used in the electric furnace is commonly known as: When it is energized, it starts heating, the furnace core temperature is about 2500 ° C, or even higher (2600 ~ 2700 ° C), and the SiC is synthesized when the charge reaches 1450 ° C (but SiC is mainly formed at ≥1800 ° C), and CO is released.

However, when the SiC is ≥2600℃, it will decompose, but the decomposed Si will form SiC with the C in the charge. Each group of electric furnace is equipped with a group of transformers, but the production of only a single electric furnace power supply, in order to adjust the voltage according to the electrical load characteristics to basically maintain constant power, high-power electric furnace to heat about 24 hours, after the power failure to generate SiC reaction is basically over, and then after a period of cooling you can remove the side wall, and then gradually take out the charge
