In this research, we reported a simple, time saving and facile method to synthesis high surface area calcium aluminate
by simple addition carbon black in the course of the solid state synthesizing.
As a reference, pure magnesium aluminate
Mg[Al.sub.2][O.sub.4] spinel was prepared using commercially available powders of MgO and boehmite (aluminium oxide hydroxide, AlO(OH)), average grain size < 0.77 [micro]m.
Biocompatibility of new calcium aluminate
hydrate phases (e.g., [CAH.sub.10], [C.sub.2][AH.sub.8], and [C.sub.3]A[H.sub.6]), that typically form in CAC systems, are prone to phase conversion phenomena .

After setting, calcium silicate hydrate (suolunite, [H.sub.2]Ca[O.sub.4]Si; card number: 98-008-7951), calcium aluminate
oxide (mayenite, [Al.sub.14][Ca.sub.12][O.sub.3]3; card number: 01-076-9897), calcium sulfate (CaS[O.sub.4]; card number: 00-043-0606), and calcium sulfate sulfite ([Ca.sub.3][(S[O.sub.3]).sub.2]S[O.sub.4], card number: 00-038- 0701) were also seen in the XRD (Figure 2(d)).
garnets are an important family of multi-functional ceramic materials.
The salicylic acid and methanol (SAM) extraction dissolves alite ([C.sub.3][S.sup.1]), belite ([C.sub.2]S), and free lime (CaO), leaving behind a residue of the tricalcium aluminate
([C.sub.3]A) and ferrite ([C.sub.4]AF) interstitial phases as well as minor phases including periclase (MgO) and alkali sulfates such as arcanite (K[bar.S]), thenardite (N[S.sub.S]), and langbeinite (K[M.sub.2] [[bar.S].sub.3]), calcium sulfates (gypsum, bassanite, and anhydrite), and carbonates (calcite and dolomite).
Wisener further informs, 'GeoKrete is completely sustainable, with an extraordinarily low carbon footprint compared to Portland or calcium aluminate
based cements because it is manufactured mostly from recycled materials ...
Results of the research showed that reduction in particle size and addition of the powder of tricalcium aluminate
nanoparticles to the raw material improve the bone growth properties.
The interaction of copper with the support is revealed through the formation of copper aluminate
To understand the physics of condensed matter, researchers are studying the interface between strontium titanate and lanthanum aluminate
, insulators that act as conductors at their interface.
