Problems solved by technology

Due to the large specific surface of the powder, the particle agglomeration is serious; the amount of organic or organic composite materials added is large, and the porosity of the green body is high, which makes sintering difficult and shrinks greatly, resulting in low product qualification rate and high production cost.
Seriously restrict the application of zirconia ceramics
