AI Technical Summary

Technical Problem

Existing ceramic materials struggle to balance high conductivity and low cost, and high-temperature sintering consumes a lot of energy. The sintering temperature of alumina powder is as high as 1650-1710℃, resulting in high energy consumption.

Method used

Conductive ceramics were prepared by using β-alumina as the main component and adding yttrium oxide, thorium oxide, zirconium oxide, molybdenum dioxide, copper oxide and zinc oxide through ball milling, spray granulation, pressing and sintering, thereby reducing the sintering temperature and improving the conductivity.

Benefits of technology

The sintering temperature was reduced by 200℃, which lowered the manufacturing cost, improved the conductivity, met environmental standards, and is suitable for the automotive, electronics, and battery industries.
