Phosphate Rock Wollastonite

Wollastonite based-Chemically Bonded Phosphate Ceramics ...

Jun 01, 2012  The Wollastonite-based CBPC is a composite material itself with several crystalline (Wollastonite and brushite) and amorphous phases (silica and amorphous calcium phosphates) . By adding PbO, only remaining PbO appears. The intensity of PbO peaks increases at the higher concentrations in the composite. Download : Download full-size image; Fig. 8.

Wollastonite-Based Chemically Bonded Phosphate Ceramic ...

The CBPCs form by acid-base reactions between an acid phosphate and Wollastonite. This reaction is exothermic. When the phosphoric acid formulation and the Wollastonite powder mixture are stirred, the sparsely alkaline oxides dissolve and an acid base reaction is initiated. The result is a slurry that hardens in a ceramic product.

Wollastonite - Wikipedia

Wollastonite is a calcium inosilicate mineral (Ca Si O 3) that may contain small amounts of iron, magnesium, and manganese substituting for calcium. It is usually white. It forms when impure limestone or dolomite is subjected to high temperature and pressure, which sometimes occurs in the presence of silica-bearing fluids as in skarns or in contact with metamorphic rocks.

QUICK-SETTING WOLLASTONITE PHOSPHATE CEMENT

Wollastonite - an overview ScienceDirect Topics

Marble is a metamorphic rock that contains predominantly of calcite (Fig. 7.4A), and/or dolomite, and minor minerals like tremolite, forsterite, spinel, garnet, diopside, and wollastonite. It occurs in regional and rarely contacts metamorphism of carbonate sediments such as limestone or dolomite, which contains a smaller or larger amount of clay.

Phosphorus removal by wollastonite: A constructed wetland ...

Jun 01, 2000  The wollastonite was then filtered out of the sample, using a 0.45 μm filter and then dried in an oven at 40°C for 24 h. The filtrate was analyzed for residual P concentration. The dried wollastonite was then used as a calcium phosphate ‘seed’ in kinetic experiments.

Research: Environmental Uses – Canadian Wollastonite

Wollastonite powder exhibited the highest removal capacity. At all phosphate concentrations, the removal was above 82%, with a maximum of almost 96%. The uptake rate was high in the first hour of the batch test and increased with increasing concentration. The wollastonite granules did not take up phosphate at concentrations below 2 mgP/l.

Wollastonite. Wollastonite is an important industrial mineral with a wide variety of applications. With its needle-like structure, the calcium inosilicate is similar to asbestos, but is non-hazardous and is used as a fire retardant, to strengthen plastics and ceramics, as a flattening agent for paints, and as an additive in friction applications.
