Explanation

ceramics made of one or more oxides. It can be divided into single components, such as aluminum oxide, beryllium oxide, titanium dioxide ceramics, etc; Composition, such as spinel, mullite, lead zirconate titanate PZT ceramics, etc. It usually has a high melting temperature and is very stable in the oxidation atmosphere. It has high mechanical strength, electrical insulation performance, and chemical stability. Except beryllium oxide ceramics, its thermal conductivity is low. Generally, ultrafine powder is used as ingredient and a small amount of sintering accelerator and modified additive are added. According to the shape and performance requirements of products, various molding methods such as hot die casting, dry pressing, isostatic pressing, tape casting, extrusion, grouting, etc. can be used. Most products are fired in oxidizing atmosphere. Sometimes vacuum, hydrogen or controlled atmosphere sintering is also used. oxide ceramics have a wide variety of applications. They can be used as structural materials, functional materials and advanced refractory. They are used in many fields such as electronics, information, laser, infrared, computer, aerospace, atomic energy, chemical industry, metallurgy, etc.
