Wollastonite powder for building materials ceramic products coating industry metallurgical manufacturing

Short Description:

Wollastonite powder, a versatile mineral composed of calcium metasilicate, finds extensive applications across various industries due to its unique physical and chemical properties. In the ceramics industry, it serves as a game-changer. For example, tile manufacturers often incorporate 10-15% wollastonite powder into their formulations. This addition significantly reduces the shrinkage rate during firing by up to 30%, minimizing the occurrence of cracks and deformations. As a result, the production yield increases, and the tiles exhibit enhanced hardness and scratch resistance, making them ideal for high-traffic areas like shopping malls and airports.

In plastics manufacturing, wollastonite powder acts as an excellent reinforcing filler. A leading automotive parts supplier added 25% wollastonite powder to polypropylene to produce lightweight door trims. The modified material not only improved impact strength by 40% but also reduced warpage, ensuring a perfect fit during assembly. This innovation helped the company cut production costs by 18% while meeting strict automotive safety standards.

The paint and coating sector also benefits greatly from wollastonite powder. When formulated into exterior paints, its acicular crystal structure creates a barrier against water and UV radiation. A case study showed that buildings coated with paints containing 12% wollastonite powder maintained 80% of their original color after three years, compared to only 60% for conventional paints.

Wollastonite

Details:

Wollastonite is a single-chain silicate mineral, the main component is Ca₃Si₃O₉. Triclinic crystal system, usually in the form of flakes, radial or fibrous aggregates. White with slight gray. Glass luster, pearl luster on the cleavage surface. Hardness 4.5-5.0 with density of 2.78-2.91g/cm³. Mainly produced in the contact metamorphic zone of acidic intrusive rock and limestone, it is the main mineral composition of skarn.

Prroduct Advantage:

Plastics industry:

In the plastics industry, wollastonite powder not only plays a filling role, but also partially replaces asbestos and glass fiber for reinforcing materials. Mainly used to improve tensile strength and flexural strength and reduce costs.

Rubber industry:

In the rubber industry, wollastonite powder is an ideal filler for rubber, not only can reduce the production cost of rubber products, but also can improve the rubber mechanical properties give special functions that rubber does not have.

Paints&Coatings industry:

In the coating industry, wollastonite powder is used as a filler for paints and coatings, which can improve the physical and chemical properties of the product, durability and weather resistance, reduce the gloss of the paint, enhance the expansion ability of the coating, reduce cracks, and can also reduce oil absorption and enhance corrosion resistance.
