Dense fused alumina fine powder 0-1mm -200 -180 -320

Dense fused alumina fine powder 0-1mm -200 -180 -320, light gray or gray-white powder. The main crystal phase of dense fused alumina is α-Al2O3. The α-Al2O3 content is more significant than 98%; the porosity is less than 4%. It is a new high-purity refractory raw material made using high-purity industrial alumina powder and reducing agent according to a certain ratio in an electric arc furnace after being melted at a high temperature. Dense fused alumina fine powder is the product passing through the finest screen in the refractory sand production line. Dense fused alumina fine powder is characterized by acid and alkali resistance, reasonable wear and corrosion resistance, and volume stability. Furthermore, it is mainly used for metallurgy, ceramics, the chemical industry, etc. It produces blast furnace troughs and castable and high-quality raw material to produce various corundum products.

Introduction of  Dense fused alumina fine powder 0-1mm -200 -180 -320:

Dense fused alumina pine powder, with α-AL2O3, as the main 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 the fused alumina series.
Dense fused alumina is fused in the furnace with the industrial alumina as the raw material; it is a new refractory material. Its characteristics are acid & alkali-proof, good grinding performance, erosion-resistant, and steady volume.

Application of dense fused alumina fine powder 0-1mm -200 -180 -320:

  • Unshaped refractory materials:
    castables, ramming materials, prefabricated refractory parts, etc
  • Shaped refractory materials:
    The refractories products for Continuous Casting

Dense Fused Alumina(FAQ)

What is a silane coating used for?

When functionalising fused alumina, a very thin layer of a silane adsorption group is applied to the fused alumina particles. This organic surface coating has the effect of better embedding and increased scratch resistance in a melamine resin matrix, for example. Fused alumina has a high refractive index (n =

What is fepa and what does it do?

FEPA is the Federation of European Producers of Abrasives. Its mission is to develop and publish standards, documents and comprehensive safety instructions for the abrasive industry. Abrasive grain sizes are produced and sold according to the FEPA standard, among other things. This is to ensure that a consistent quality for

What is the specific surface?

The specific surface means the outer surface of a substance including all accessible pores in relation to the mass. It is determined using the Brunauer-Emmett-Teller (BET) method.

Why is corundum or silicon carbide used?

Corundum is the most frequently used abrasive. The purer the corundum, the harder it also is, which can be determined from the colour. The toughness can be increased by adding various metal oxides and by shortening the cooling process in production. The following distinctions are made: Brown fused alumina with
