CALCIUM ALUMINATE Usage And Synthesis

Chemical Properties

white, monoclinic, tricl, or rhomb; -200 mesh 99% powder(s) [CER91] [CRC10]

Physical properties

Calcium aluminate is a white powder and exhibits a monoclinic crystalline form. Its density is 2.98 g/cc and its melting point is 1605 °C.

Uses

The major use found for CaAl2O4 has been as a hydrous cement. Alternative names are “aluminous cement”, “high-alumina cement” (HAC) and “Ciment fondu”. They are used in a number of small-scale, specialized applications.

Uses

Calcium aluminum oxide is used as a precursor in the production of naphtha steam reforming catalysts, refinery gas steam reforming catalysts, aluminum chlorohydrate, secondary hydrocarbon steam reforming catalysts. It is also used in the production of refractory and cements.

Preparation

Calcium aluminate can be formed by heating the oxides together at about 900–1250 °C:
CaO + Al2O3 + heat→CaAl2O4
