High hardness. Most metals and alloys can be processed using the melting and casting route, but we typically do not choose to apply this method for the processing of specific metals (e.g., W) and most ceramics. The hardest substances known, such as diamond, boron carbide, cubic boron nitride and silicon carbide are ceramics. However, recently, most advanced ceramics are made of carbon, sulfur, metallic elements, and nitrogen. The delivery of this course is very good. It's hard to imagine not having mobile phones, computers, television and other consumer electronic products. Synthesis of powder involves getting it ready for shaping by crushing, grinding, separating impurities blending. A ceramic is often said to be a inorganic, nonmetalic solid made from a powder which is then hardened by heating and cooling. Ceramics can be excellent insulators, semiconductors, superconductors and magnets. 3.
