Mg-PSZ powder for ceramic grade
With special production process, we can produce different Mg-PSZ powder by adjusting the content of MgO.
Our Mg-PSZ powder can be divided into two types. One is white and the other is yellow and earth yellow, which
are applied for different structural ceramics, anti-corrosion ceramics and Refractory ceramics.
