High Alumina Powder

High alumina powder is made of high alumina bauxite clinker through crushing, iron removal and other machining processes. It is characterized by high aluminum content, low iron content, high hardness, low coefficient of thermal expansion, high refractoriness, stable thermochemical properties, etc.

Common sizes:

Usual sizes: 0.150mm, 0.016mm, 0.075mm, 0.053mm, 0.045mm; other sizes can also be processed according to requirements.

Application:

High alumina powder is the main raw material for making foundry coatings, refractory bricks, pouring materials, iron ditch materials, refractory furnace materials, refractory materials and other unshaped refractory materials.

Characteristics of high alumina fine powder:

Bauxite clinker is divided into GAL50, GAL60, GAL70, GAL80, GAL85 and GAL88 according to physical and chemical indexes.
