Ceramic Square Alumina Crucibles

Zirconia porcelain ball  is a tremendous shape of packages of inorganic non-metal grinding medium, specially implemented in grinding and dispersion of  maximum important areas, our organization especially produces grinding with zirconium balls, particularly concerned in the sand mill inner, dispersion is in particular concerned in immoderate-tempo mixing mill internal. zirconia beads are crafted from micron-degree and sub-nano zirconia and yttrium oxide as uncooked materials thru superior era to make numerous technical symptoms and performance symptoms to achieve the worldwide fashionable diploma. especially utilized in exceedingly-first rate grinding substances that require "zero pollutants" and high viscosity and immoderate hardness materials.

Zirconia crucibles---- refractory grade crucibles:(density is 4.5g/cm3)

They have cxcellent chemical inertness and a very good thermal shock at tempertures to 2000℃, better corrosion resistant to acids and alkalis ,widely used in superalloy and precious metals industries, such as induction melting crucibles for specialist steel, glass melting, precious and other metals melting.
