| Hazard Information | Back Directory | [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]
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. | [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. | [Preparation]
Calcium aluminate can be formed by heating the
oxides together at about 900–1250 °C:
CaO + Al2O3 + heat→CaAl2O4 |
