STRONTIUM ALUMINATE Usage And Synthesis

Physical properties

The crystals of SrAl2O4 are monoclinic, with unit-cell parameters: a = 5.1497 ? , b = 8.836 ? , c = 8.442 ? , β = 93.43°; space group P2₁ or P2₁/m.

Uses

The SrO·Al2O3 system is of interest in industry because of the use of the intermediate compounds for hydraulic cements, laser matrices, and long-duration photoluminescence or thermoluminescence pigments.

Uses

Strontium aluminate acts as a photo luminescent phosphor with long persistence of phosphorescence.

Preparation

Strontium aluminate can be prepared by reaction of the oxides at about 700–900°C:
SrO + Al2O3 + heat→SrAl2O4
