What kind of material is refractory bauxite?

What kind of material is refractory bauxite?

Answer:

In China it is generally believed: "Bauxite ore refers to the mineral with a fairly high aluminum content (over 40%), and aluminum silicon ratio is greater than 2.5 (A / S≥2.5). Minerals with an aluminum content less than this value is called clay ore or allite shale or aluminious rock. " In China, it has been explored that monohydrate bauxite ore accounts for about 98% of the total reserves of bauxite.
Bauxite in refractory industry usually refers to the calcined bauxite ore which contains Al2O3 no less than 48%, while the content of Fe2O3 is rather low. Clinker of bauxite with high alumina is calcined bauxite. Tghe clinker is grey, light yellow and dark gray.
Bauxite (aluminous soil; bauxite), also known as alumina or bauxite ore whose main component is alumina oxde, is a hydrated alumina containing impurities. It is an earthy mineral. It is white or gray, and as it contains iron, it is also brownish yellow or light red. Density of 2.4-2.5g / cm3, hardness 1-3, opaque and crispy. It is extremely difficult to melt.
Refractory bauxite, also known as bauxite alumina or bauxite with high alumina, is the main raw material for the production of high alumina (aluminum content ≥48%, belongs to LAS) refractory.
Bauxite, also known as bauxite alumina or bauxite with high alumina, is the main raw material for the production of high alumina (aluminum content ≥48%, belongs to LAS) refractory. It must be calcined bauxite ore.
