In the arts, silicon carbide is a popular abrasive in modern lapidary due to the durability and low cost of the material. In manufacturing, it is used for its hardness in abrasive machining processes such as grinding, honing, water-jet cutting and sandblasting. Particles of silicon carbide are laminated to paper to create sandpapers and the grip tape on skateboards. WebCopper grain growth and strength Pure copper (typically >99.9%) is a great electrical conductor, and in some applications its strength is important as well. Copper grain growth closely follows Feltham's observation, i.e. D2-D2 = kot exp (-Ho/KT). For this problem, ignore temperature dependence and use D.D. ? = constant.
