High Quality Raw Materials Wollastonite Powder

Product Description

Product Description
Wollastonite
Introduction:
Wollastonite is composed of Ca3 [Si3O9].Triclinic system.They are usually lamellar, radial, or fibrous aggregates.White microstripe gray.Glass luster, cleavage surface pearl luster.Hardness is 4.5 ~ 5.0.The cleavage parallel {100} is complete and the parallel {001} is medium. The intersection Angle of the two cleavage planes is 74°.Density 2.78~2.91 g/cm3.It is mainly produced in the contact metamorphic zone between acidic intrusive rock and limestone, and is the main mineral component of skarn.In addition, it is found in some deep metamorphic rocks.Used as: raw materials or fillers for papermaking, ceramics, cement, rubber, plastics, etc.Gas filtration materials and heat insulation materials;Metallurgical fluxes, etc.

Applications:
1, ceramic industry: ceramic raw materials by adding the right amount of wollastonite, can significantly reduce the firing temperature, shorten the time of firing to achieve a fast low-temperature firing, a large number of fuel savings, significantly reduce product costs. At the same time, improve the mechanical properties of products, reduce product cracks and stripes, improve product yield.
2, paint and coatings industry: in the paint with wollastonite filler or emulsion, you can get high-quality bright colors of paint, and have the coating and anti-aging properties. White wollastonite is a good raw material for high-quality white paint and soft pastel paint, easy to brush, the surface of a slide, has a high resistance to weathering.
3, rubber and plastics industry: rubber and plastic can be done to strengthen the filler, with the thermosetting and thermoplastic resin and mold resin model, with good thermal shock resistance and enhance stability. Filled in the epoxy resin, before plastication has low water absorption, low dielectric constant and low viscosity, good performance.
4, other aspects: wollastonite can also be used for steelmaking slag, welding electrode coating, ceramic mold, grinding materials and grinding wheel production, paper filling agent, the production of white cement, manufacturing special electrical ceramics and other rare minerals raw material.
