Characteristics and application of barium titanate ceramics

Barium titanate ceramics are ceramic materials with barium titanate (BaTiO3) or its solid solution as the main crystal phase. The main raw materials are barium carbonate and titanium dioxide. Generally, barium titanate is synthesized at 1200℃ first, and then modified oxide is added. After fine grinding, it is sintered at 1400℃ or so. Used as dielectric material of capacitor and make many kinds of piezoelectric devices Barium titanate ceramics are ceramics with barium titanate or its solid solution as the [...]

Types and applications of new ceramic materials

Several new ceramic materials are mainly introduced. 1. Engineering ceramics Engineering ceramics, it is mainly used in high temperature, also known as high temperature structural ceramics. This kind of ceramic takes alumina as the main raw material, which has the advantages of high strength, high hardness, high oxidation resistance, corrosion resistance, wear resistance, ablative resistance and so on under high temperature. It can withstand the high temperature of 1980℃ in the air. It is an important material in space technology, military [...]

There are seven requirements for an ideal anode material

The ideal anode material must have the following seven conditions: low chemical potential, and the anode material to form a large potential difference, so as to obtain a high power battery; High cycle capacity should be available; In the anode material, Li+ should be easy to be embedded and detached, with higher coulombic efficiency, so that the charging and discharging voltage can be relatively stable in the process of Li+ removal. Good electronic and ionic conductivity; Good stability, electrolyte [...]
