Calcined Alumina is a commercial Alumina or Aluminum Oxide. It is white powder. One of the outstanding characteristics of Calcined Alumina is its hardness which is 9 on mohs scale. There is board industrial field of applications for this type of alumina and number of distinctive grade are produced to meet various needs.

Identification of Grades -
1) Calcined Aluminum S-100 grades : White granular free flowing powder passes through 150 m.
2) Calcined Aluminum S-300 grade : White superfine powder passes though 45 micron.
3) Calcined Alumina SCM grade : It is finally ground grades consisting entirely of superfine passes through 45 micron.
4) Calcined Alumina S-300 PT : It is finely ground grade consisting entirely of superfine with surface treated

Use as a bedding material in the heat treatment of special alloy steels, It is use as a fluxing medium in the meeting of special steels as a component of low expansion glass. It is use as a constituent of special china dazes & it is use as a raw material for the manufacture of dental porcelains. It is use for refractory application such as electrical insulators. It is use as a abrasive resistant. It is use glazing ceramic tiles.
