"Rational Use of Clays: Electric Porcelain" is a technical book that explores the technological significance of non-metallic minerals, particularly clays, in the ceramic industry. It provides a detailed analysis of the molecular structure and composition of clay minerals that are crucial for the production of ceramic products. The book discusses the manufacturing of electric porcelain, which is considered an excellent insulating material due to its high electrical resistance. The research focuses on the dosing and production of electric porcelains from clay and kaolin varieties mined in the rural mines of Popayán, Colombia. By using the triaxial method, the optimal mixture for ceramic shaping is determined, followed by a sintering process for the electrical characterization of the produced parts. This book is a valuable resource for professionals and students engaged in the application of clays in the modern ceramic industry.
