Developments in Ceramic Materials Research

ceramics Are Refractory, Inorganic, And Nonmetallic Materials. They Can Be Divided Into Two Classes: Traditional And Advanced. Traditional Ceramics Include Clay Products, Silicate Glass And Cement; While Advanced Ceramics Consist Of Carbides (sic), Pure Oxides (al2o3), Nitrides (si3n4), Non-silicate Glasses And Many Others. Ceramics Offer Many Advantages Compared To Other Materials. They Are Harder And Stiffer Than Steel; More Heat And Corrosion Resistant Than Metals Or Polymers; Less Dense Than Most Metals And Their Alloys; And Their Raw Materials Are Both Plentiful And Inexpensive. Ceramic Materials Display A Wide Range Of Properties Which Facilitate Their Use In Many Different Product Areas. This New Book Presents Leading-edge Research In This Field From Around The World.
