Short Description:

Wollastonite, also known as wollastonite powder or needle wollastonite, is a naturally occurring silicate fibrous mineral primarily composed of calcium silicate (CaSiO₃). It typically appears white or gray and is commonly found in metamorphic limestone. In welding fluxes, advanced equipment such as shear grinding can produce needle-shaped wollastonite powder. This form of wollastonite enhances the performance of welding materials.

    Features_.png

    Wollastonite can reduce the sintering temperature and shorten the sintering time, achieve a low-temperature sintering, and can save a lot of fuel, at the same time improve the mechanical properties of the products, reduce crazing, crack, breakage, enamel defects, such as warping and problems. It can also improve green strength, reduce the product weight, increase luster glaze, reduce the glaze mud viscosity.


    Application Fields

    1.Ceramic Grade Wollastonite suitable for glaze industry, engobe industry, tableware industry, ceramic body blending, glass industry, and paint industry.

    2.Metallurgical Grade Wollastonite used in continuous casting flux, agglomerated flux, welding electrodes.

    3.Wollastonite Needle Powder is widely used in plastic, rubber, paint and coating, ceramic, frictional materials, insulator, building materials, composite materials and other fields.
