Abstract:


Electronic ceramics have been widely investigated because of their useful properties for various applications. These ceramics exhibit excellent properties such as dielectric, piezoelectric, semiconducting, pyroelectric, electro-optic, magnetic, and superconducting properties. They are usually produced via the conventional mixed oxide route. Raw materials are mixed before calcining. The calcined powder is then pressed into green pellets. The green pellets are sintered for densification and grain growth. The reaction-sintering process for preparing electronic ceramics is simple and effective. Calcination of the conventional mixed oxide route is conducted in the heating up period. Therefore, the calcination and the following pulverization are bypassed, saving both time and expense. This review paper examines reports about electronic ceramics prepared via the reaction-sintering process and recent patents also.
