Evaluation of Calcium Aluminate/Calcium Phosphate Based
The curing of calcium aluminate cement occurs with high water consumption during setting and hardening of prepared pastes. The relatively high strength values of calcium aluminate pastes compared to those of calcium phosphate and also wide range variations in the consistency and formulations make it suitable for a wide range of applications 3 4. Nanocrystalline calcium aluminate (CaAl2O4and Ca3Al2O6) powders have been prepared by pyrolysis of complex compound of aluminium and calcium with triethanolamine (TEA). The soluble metal ion-TEA complex forms the precursor material on complete dehydration of the mixtures of the complex of calcium-TEA and aluminium-TEA.

Calcium aluminatesWikipedia
Calcium aluminates are a range of materials obtained by heating calcium oxide and aluminium oxide together at high temperatures. They are encountered in the manufacture of refractories and cements. The stable phases shown in the phase diagram (formed at atmospheric pressure under an atmosphere of normal humidity) are The product obtained after cooling is a hard mineral calcium aluminate clinker. Crushed or screened it is used as an aggregate. The composition and colourranging from the purest white to jet blackdepends on the proportion of each raw material. Ground into a fine powder the clinker becomes calcium aluminate cement (CAC) which forms a

Calcium aluminate cement is a kind of refractory material and binder which can not only be used as castable refractory but also be used in monolithic refractory as binding agent. For instance it can be used as the binder of high alumina castable corundum castable Calcium aluminate cement is cement formed from the combination of limestone and alumina at high temperatures. It is used in specialized cement applications where resistance to extreme temperatures mild acids and alkalies sulfates and water are necessary. It is also used in situations where rapid strengthening is required.

Chemical Synthesis and Characterization of Calcium
The Pechini process was used to produce high‐purity monocalcium aluminate (CaAl 2 O 4) powders at temperatures as low as 900°C. Absorption spectrometry and BET measurements revealed particles with sizes ranging from submicrometer to 100 μm with specific surface areas as high as 10 m 2 /g. Calcined Alumina is a commercial Alumina or Aluminum Oxide. It is white powder. One of the outstanding characteristics of Calcined Alumina is its hardness which is 9 on mohs scale. There is board industrial field of applications for this type of alumina and number of distinctive grade are produced to meet various needs.

Calcium Aluminatean overview ScienceDirect Topics
Calcium aluminate cements (CACs) represent an interesting alternative because their pore water pH ranging from 11.4 to 12.5 is reduced as compared to OPC (Goñi et al. 1991 ). The main difference between Portland and calcium aluminate cements lies in the nature of the active phase that leads to setting and hardening.
