factory low price Aluminium Sulphate Powder - Calcined Alumina For Refractories – Ton Year

Calcined Alumina
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.

Uses
