Here we discuss the physical and chemical properties of Silicon Dioxide nanoparticles, and their appliions in various sectors. Silicon dioxide (SiO 2) is a compound of Silicon and Oxygen, commonly called silica and the elements are linked by the covalent bond.
carbide grinding sintered
Silicon Carbide is among the hardest of ceramics, and retains hardness and strength at elevated temperatures, which translates into among the best wear resistance also. Additionally, SiC has a high thermal conductivity, especially in the CVD (chemical vapor deposition) grade, which aids in thermal shock resistance.
