High-Temp Zirconia Foam Ceramic Filter for Metallurgy & Casting, 10-20 PPI, 80-90% Porosity, 1 Piece 100mm (3.94") Dia x 22mm (0.87") Thick Round

Model: Zirconia Foam CeramicPore density：8-60ppi；Porosity：80-90%；Fire resistance：≤1500℃；Bending strength：>0.8Mpa；compressive strength：>0.9Mpa；Bulk density：0.35-0.5g/cm³；Thermal shock resistance：6times/1100℃Foam ceramics are the third generation porous ceramics, which are newly developed after ordinary porous ceramics and honeycomb ceramics. Foam ceramics can form with many twists and turns of numerous tiny holes, which have many advantages such as , high temperature resistance and good filtration and adsorption. They can be widely used in metallurgy, casting, chemical industry, environmental protection, light industry food and saving. The porosity is more than 80%, the tensile strength is 2.2MPa, the softening temperature is more than 1500 ℃
