What is STRONTIUM ALUMINATE?
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.
The Uses of STRONTIUM ALUMINATE
Strontium aluminate acts as a photo luminescent phosphor with long persistence of phosphorescence.
The Uses of STRONTIUM ALUMINATE
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.
Preparation
Strontium aluminate can be prepared by reaction of
the oxides at about 700–900°C:
SrO + Al2O3 + heat→SrAl2O4
