An exploration of electric refractory materials, this book covers developments of blue light-emitting diodes using GaN-based nitrides for laser and high-temperature and -frequency devices. Electric Refractory Materials introduces growth and evaluation standards of films and bulk crystals, with consideration of band structure, surface electronic structure, and lattice vibrations. It also covers heat capacity and thermal conductivity, irradiation properties, and selective surfaces. Focusing on diamond material, the book examines its synthesis and characterization as well as its electrical, optical, and conductive properties. The book also discusses the use of silicon carbide, boron compounds, and other material used in electronic and light-emitting devices.

HIGH ELECTRICAL RESISTANT MATERIALS The book describes how the utilization of high-carbon slag/pond ash/fly ash for making value-added ceramics is useful for the electrical sectors. Since waste materials are currently endangering our environment, ways of utilizing them have become a global challenge. Currently, R&D work is being carried out to utilize these materials for producing value-added products. This book details the investigations to utilize fly ash (FA) and pond ash (PA) - both waste materials from thermal power plants - with high-carbon ferrochrome (HCFC) slag (by-product of the ferrochrome industry), for producing a novel material for ceramics. Kaolin/K-feldspar is mixed with PA/HCFC slag to produce ceramics with the formation of mullite. The FA/PA/HCFC slag-based ceramics can replace porcelain-based ceramics, and some permanent ceramic structures can be constructed with such wastes. Properties and structures made with ceramics are found to be comparable with those made with porcelain-based ceramics. Performances of these materials above ambient temperature have been evaluated and results indicate the possible replacement of porcelain with these newly invented ceramics. Audience The book will be used by electrical and civil engineers in the electrical, construction, and ceramic industries as well as the industrial waste sector. Researchers in materials science, structural, civil and electrical engineering, environmental science, and ceramic engineering, will also have high interest.
