Silicon carbide sintering furnace is a kind of machine used in industry. In fact, it is an intermittent induction heating furnace. It is mainly used in carbide and powder metallurgy industries to produce metal powder and composite metal powder with various particle sizes, such as tungsten carbide powder, titanium carbide powder, vanadium carbide powder, etc.
Pressureless sintering of silicon carbide powder requires addition of sintering aids and high sintering temperature (>2100 C) in order to achieve high sintered density (>95% T.D.). The high sintering temperature normally causes an exaggerated grain growth
This technique utilizes a polymer precursor, AHPCS, in accordance with low temperature sintering to enhance the density of silicon carbide. This procedure is environmentally friendly and makes use of low temperature and pressure processing parameters.

The subject disclosure relates to methods and machine systems used in the sintering of silicon carbide and other ceramics. BACKGROUND Although conventional ceramic production techniques date to the Sumerians, rudimentary efforts to harden natural raw materials nearly 5000 years ago, the 20 th
Silicon carbide ceramics with various microstructures were fabried by controlling the amount and composition of a Y2O3-Al 2O3 liquid phase, crystallographic phase of the starting powders, trace impurities in those powders, and time and temperature of sintering and post- sintering heat-treatments. Alpha and beta SiC "seeds" were used to control grain growth during sintering. The grain size
