Microwave sintering on cobalt oxide, cobalt sulfate, lithium cobalt oxide

Microwave sintering is a method that uses the special wave band of microwave to couple with the basic fine structure of the material to generate heat. The dielectric loss of the material in the electromagnetic field causes the entire material to be heated to the sintering temperature to achieve densification. The principle of microwave sintering is essentially different from the current conventional sintering process. Since the material can uniformly absorb microwave energy and be heated internally and externally, the thermal gradient and heat flow direction inside the sintered object in the microwave field are completely different from those during conventional sintering.
Microwaves can achieve rapid and uniform heating without causing cracking of the sample or the formation of thermal stress within the sample. More importantly, rapid sintering can form a uniform fine-grained structure and higher density inside the material, thereby improving material performance. At the same time, because different components within the material absorb microwaves to different degrees, selective sintering can be achieved, thereby preparing materials with new microstructures and excellent properties.

Microwave sintering equipment can be used to sinter various high-quality ceramics, lithium cobalt oxide, silicon nitride, silicon carbide, alumina, aluminum nitride, zirconium oxide, magnesium hydroxide, aluminum, zinc, kaolin, cobalt sulfate, cobalt oxalate, five Vanadium oxide, phosphogypsum/gypsum, etc.; sintered electronic ceramic devices: PZT piezoelectric ceramics, varistor, etc.
