Плотные корунд

Description: Dense corundum, with a-AL2O3, as main principle crystalline phase, gray, is characterized by high melting point,high bulk density, low apparent porosity,excellent wear resistance,slag resistance, steady volume and thermal shock resistance. It is an excellent refractory material in corundum series. Advantages: 1) Weare manufacturer rather than trading companies, thus: 2) we are more specialized in the procuction. 3) we can offermorecompetitive price 4) we can produce as per customer's requirement Chemical and physical analysis CHEMICALCOMPOSITION GRIT >0.1mm TYPICALVALUE FINEPOWDER ≤0.11mm TYPICALVALUE AL2O3%≥ 99 99.2 98.6 99.0 SiO2%≤ 1.0 0.4 1.0 0.45 Fe2O3%≤ 0.15 0.1 0.3 0.2 TiO2%≤ 0.1 0.05 0.1 0.05 CaO%≤ 0.1 0.05 0.1 0.05 MgO%≤ 0.1 0.05 0.1 0.05 NaO2%≤ 0.1 0.05 0.1 0.08 C%≤ 0.1 0.08 0.12 0.1 ApparentPorosity%≤ 2.0 0.8 2 0.8 Bulkdensity (g/cm³)%≥ 3.90 3.93 / / Truedensity (g/cm³)%≥ 3.96 3.99 3.96 3.98 Contact information: Tel: +86-371-64673686 Fax: +86-371-64609186
