Wollastonite powder is white with slight gray or red tints, in the form of flaky, radial or fibrous aggregates. It belongs to the triclinic crystal system, has a glassy luster, and the cleavage shows a pearl-like luster.Silica feldspar is a calcium silicate mineral with needle-like and fibrous crystal forms, high whiteness, and unique physical and chemical properties.
1.Inherent Needle-like Structure: This is the core value of wollastonite. Its crystals naturally grow into needle-like or fibrous forms .During processing, with proper techniques, its high aspect ratio (the ratio of length to diameter) can be maximally preserved. When added to materials, these tiny "needles" act like steel bars, forming a network structure within the material, thereby providing reinforcement and toughening effects
2.The "Flux Master" for Energy Saving and Consumption Reduction: In ceramic production, wollastonite is a real "lucky charm." It has a relatively low melting point (approximately 1540°C) and can form eutectic mixtures with other components, significantly lowering the firing temperature of ceramic bodies and shortening the firing cycle . Data shows that after introducing wollastonite, the firing cycle of ceramics can plummet from 90 hours to just 50 minutes, with energy consumption reduced by nearly half.
3.A Stable and Reliable "Top Performer" in Performance: Wollastonite boasts stable chemical properties, with excellent resistance to acids, alkalis, corrosion, and weathering. Its low thermal expansion coefficient helps prevent ceramic body cracking ; its low oil absorption allows for more "economical" resin usage in coatings ; and its low electrical conductivity coupled with good insulation meets the demands of the electronics and electrical fields

1.Ceramic industry: As a raw material or additive for ceramics, it improves the mechanical and sintering properties of the products, reduces the firing temperature and cycle, enhances the whiteness and fluidity of the glaze, and reduces the pinholes on the products.
2. Coatings and Paints: Used as fillers, they enhance the hardness and wear resistance of the coating film. They can replace some titanium dioxide and reduce costs, thereby improving the tensile strength and corrosion resistance of the coating.
3. Plastics and rubbers: As fillers, they enhance the strength and heat resistance of the reinforcing materials, and can partially replace glass fibers as the reinforcing elements in polymer composite materials, thereby reducing costs.
4. Metallurgical industry: Used as a flux for blast furnace ironmaking, as well as metallurgical protective slag, to enhance the smelting efficiency and adsorb harmful inclusions in the molten steel.
5. Building materials: Used for manufacturing environmentally friendly building materials such as lightweight bricks and insulation boards, to enhance impact resistance and bending strength by 12%.
6. Electronics industry: Used for manufacturing insulating materials and electronic components.
7. Paper Industry: As a filler, it enhances the whiteness and opacity of the paper, and improves the printability of the paper.
8. Other applications: including use as a substitute for asbestos, for the preparation of bioactive materials, as a raw material for white carbon, and as a type of silicon fertilizer, etc.
