Introduction


Calcined bauxite is one of the principal ore of aluminum. Calcined bauxite is obtained by calcining (heating) superior grade bauxite at high temperature (from 850℃ to 1600℃). This removes moisture thereby increasing the alumina content. Compared to an alumina content of about 57% to 58% in raw bauxite, calcined bauxite has an alumina content of 84% to 88%. 


The calcined bauxite can be processed into bauxite sand and bauxite powder of different particle sizes, both of which can be directly used as refractory sand. It has a very high status in the field of refractory materials. We are not only bauxite supplier, but also your loyal partner who can provide qualified products.



SEPPE Bauxite Sand Features & Advantages 

1. Lower thermal expansion rate and thermal conductivity: It is just this characteristic that makes the foundry more precisely, less cracking and high output. Improve foundry quality. 

2. Lower cleavage breakage rate: It has high density and has very low cleavage breakage rate. Easily reclaimed that makes it more protect environment for the less sand powder occurred.  

3. High refractoriness and service temperature: Major element is Al2O3 that has very good refractoriness.
