Extractive metallurgy deals with the extraction of metals from naturally occurring compounds and the subsequent refinement to a purity suitable for commercial use. These operations, known as refining of metals, follow mining and beneficiation of the ore (see Figure). The selection and design of the extractive …
Refractories are a type of ceramic material that can withstand high temperatures under various environmental conditions. Some refractories such as carbides, nitrides, and oxides (SiO2, Al2O3, SiC, and MgO) having a high melting point and wear resistance are used in extractive metallurgy, cement kilns and glass …
The use of ceramic materials in science and industry is very widespread because of their important advantages over metals and polymers at high temperatures or in corrosive environments. Some application of ceramic materials in different areas are as follows: Traditional Ceramics Traditional ceramics are comprised of …
Ceramic materials are inorganic and non-metallic materials. The crystal structure of ceramics is more complex because at least two elements are involved in making a ceramic compound. The ceramic materials exhibit useful properties like strength and hardness, high melting temperatures, chemical resistance, low thermal, and electrical …
