Biological and microbiological behavior of calcium
Dec 23 2019 · Calcium aluminate cement (CAC) as a biomaterial has been evaluated for its physical mechanical and biocompatibility properties. Furthermore the application of CAC for bone repair is due to its composition and coefficient of thermal expansion which is similar to that of human bone. Thus the aim of this study was to evaluate compositions of CAC-based blends as substitutes for bone defects.

Calcium aluminate cement in refractory applications
Calcium-mono-aluminate (CA or CaAl 2 O 4) and calcium-di-aluminate (CA 2 or CaAl 4 O 7) are the main phases in iron free high alumina cements (CAC) which are used in demanding refractory applications. It is well known that the hydraulic reactivity of calcium aluminate phases increases with the calcium content of the phase and therefore CA
