Alumina ceramic foam filter

Introduction

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 strength, high temperature resistance and good filtration and adsorption. They can be widely used in metallurgy, casting, chemical industry, environmental protection, light industry food and energy saving. The porosity is more than 80%, the tensile strength is 2.2MPa, the softening temperature is more than 1500 ℃; the materials are aluminum oxide, magnesium oxide and silicon carbide. The special-shaped products can be prepared according to the needs, with small specific gravity, corrosion resistance and erosion resistance
