Calcined alumina
Calcined alumina bụ a azụmahịa alumina ma ọ bụ Aluminium oxide. Ọ dị ọcha ntụ ntụ. Otu n'ime ihe ndị pụtara ìhè e ji mara Calcined alumina bụ ya ekweghị ekwe nke bụ 9 on mohs n'ike. E nwere osisi na ulo oru ubi nke ngwa maka ụdị alumina na ọnụ ọgụgụ nke pụrụ iche na klas na-emepụta izute dị iche iche na mkpa.
Identification nke akara ule
1) Calcined Aluminium S-100 akara ule: White granular free etoola powder agabiga 150 m.
2) Calcined Aluminium S-300 ọkwa: White ọkasị mma powder aga ezie 45 micron.
3) Calcined alumina SCM ọkwa: Ọ bụ akpatre ground akara ule esịnede kpamkpam nke superfine-agabiga 45 micron.
4) Calcined alumina S-300 pt: Ọ na-finely ground ọkwa esịnede kpamkpam nke ọkasị mma na n'elu mesoo.
Eji
Iji dị ka a eji ehi ura ihe onwunwe ke okpomọkụ omume nke pụrụ iche alloy steels, Ọ bụ iji dị ka a fluxing ajụ na nzukọ pụrụ iche steels ka a akụrụngwa nke ala mgbasa iko. Ọ na-eji dị ka a constituent nke pụrụ iche china dazes & ọ bụ iji dị ka a akụrụngwa n'ihi na imewe nke eze porcelains. Ọ bụ iji maka refractory ngwa dị ka eletriki insulators. Ọ bụ iji dị ka a abrasive eguzogide ọgwụ. Ọ bụ iji gbazere agbaze seramiiki taịl nile.
A pụrụ iche nke Alpha calcined alumina.
Dị ka kwes mkpuchi dịanyā polima, ọ na ọtụtụ-eji thermal conductivity nke plastik, roba, adhesives na coatings.
