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