Biocompatibility and bacterial infections are the primary concerns associated with current bone graft substitutes. The application of wollastonite-based scaffolds for tissue engineering becomes a novel subject interest. In present study, single phasic wollastonite scaffold was synthesised using citric acid-based sol–gel combustion route. Its physicochemical characteristics, antibacterial proper...

This article presents an investigation on the application of amino acids to control CaCO3 crystallization in carbonation cured wollastonite composites. It was observed that carbonated without any acid formed calcite as primary polymorph CaCO3. In contrast, use admixtures resulted formation stable amorphous calcium carbonate (ACC), vaterite, and aragonite during wollastonite. The composites prod...

Solubilities of corundum (Al2O3) and wollastonite (CaSiO3) were measured in H2O–NaCl solutions at 800 C and 10 kbar and NaCl concentrations up to halite saturation by weight-loss methods. Additional data on quartz solubility at a single NaCl concentration were obtained as a supplement to previous work. Single crystals of synthetic corundum, natural wollastonite or natural quartz were equilibrat...

Zoned, silica-deficient, calcic garnets containing up to 5 mol% F substitution for 0 formed during contact metamorphism of basalts by the Skaergaard intrusion in East Greenland. Fluorian calcic garnets occur as a retrograde alteration of prograde wollastonite and clinopyroxene that fills vesicles and vugs in lavas 30-70 m from the intrusion. Paragenetically equivalent phases include fluorite, w...

The potential of the tailings from Morille scheelite-bearing calc-silicate deposit as a commercial raw material for inert glass–ceramic was determined. Nucleation and crystal growth temperatures glass were studied. maximum nucleation rate parent are 612 °C 660 is at 776 1047 °C. At nepheline, wollastonite akermanite formed. In glasses treated higher temperature nepheline becomes unstable wollas...

Sulfate attack is a series of physico-chemical reactions between hardened cement paste and sulfate ions. Sulfate ion penetration into the hydrated cement results in the formation of voluminous and deleterious phases such as gypsum and ettringite which are believed to cause deterioration and expansion of concrete. Concrete deterioration due to sulfate attack depends on many parameters, however, ...

Apatite-wollastonite (A-W)-phlogopite glass-ceramic is considered to be difficult to resorb, but often, it has been incorporated in particulate form to create new bioactive composites for potential maxillofacial applications. With various compositions, the present work has attempted to prepare apatite-wollastonite (A-W)-phlogopite glass ceramic composites, by applying sintering. Here, three-poi...
