Some methods to improve wetting condition were applied: alloying of the melt. In order, to reduce melt surface tension, % magnesium was introduced into the metallic bath. Magnesium also can react with the oxygen presents at the surface of silicon carbide particles favouring direct contact of the components. overheating of the liquid matrix. The temperature of the melt was 868°C.
Cracks in the silicon carbide then propagate through the carbon layers resulting in failure of the particle. Once the silicon carbide layer thickness exceeds a critical value, the load required to initiate cracking of the silicon carbide exceeds the crush strength of the underlying particles.
The new multiphase silicon carbide ceramic is affixed as an lining material or embedded in the surface of related equipment, which can greatly improve the wear and corrosion life of the equipment. The abrasion resistance of the wearresistant particles is three times that of alumina (corundum) ceramics and five times that of highalloy wearresistant cast steel.
Silicon carbide (SiC) nanoparticles exhibit characteristics like high thermal conductivity, high stability, high purity, good wear resistance and a small thermal expansion coefficient. These particles are also resistant to oxidation at high temperatures.

Silicon carbide (SiC) is a promising candidate for thermoelectric applications because SiC has a large Seebeck coefficient and a low electrical resistivity [9, 10]. However, SiC exhibits poor thermoelectric performance owing to its high thermal conductivity (~120 W m −1 K−1) [11, 12], despite having a high power factor. In this regard,
