Which Industries Benefit Most from Our Zirconium Silicate Powder?
Zirconium silicate powder serves as a high-performance opacifier and structural filler in a wide range of industrial applications. In the ceramic industry, it is commonly used in floor tiles, porcelain slabs, sanitaryware, household tableware, rustic pottery, and special porcelain to enhance glaze opacity, whiteness, and firing stability. It also plays a key role in the formulation of plastic compounds—especially epoxy, silicone, and ethylene resins—where it improves thermal resistance and dielectric strength. For refractories, it supports high-temperature performance in castables, kiln components, furnace linings, and refractory cement, delivering consistent durability under extreme conditions.
Ceramic Industry
The ceramic industry is the primary application area for zirconium silicate powder, especially in glazes for architectural ceramics, daily-use ceramics, and sanitary ceramics.
As an Opacifier, it is used in various types of ceramic glazes, such as floor tiles, large rock slabs and other building ceramics, toilets, wash basins and other sanitary ware, exported coffee cups, bowls, dishes, tableware and other daily ceramics, coarse ceramic utensils, special porcelain, etc.
It can also be used in the ceramic sticks and brake pads industry. Cars, trucks, ships, airplanes, etc., use zirconium products of varying sizes depending on the parameters of their brake systems. The finer the product, the larger the particle contact area during braking, resulting in superior braking performance.
Ceramic Glazes: Zirconium silicate powder is the most important opacifier and whitening agent in ceramic glazes. Due to its high refractive index and good chemical stability, it can impart excellent whiteness, gloss, and opacity to the glaze surface, while also improving the hardness and wear resistance of the glaze. Zirconium silicate powders of different particle sizes can be used to produce matte, semi-matte, or glossy glazes.
Ceramic Bodies: In certain special ceramic bodies, zirconium silicate powder can also be used as an additive to improve the sintering performance, mechanical strength, and thermal shock stability of the body.
Refractory Materials
The high melting point, low thermal expansion coefficient, and good chemical stability of zirconium silicate powder make it an ideal choice for producing high-performance refractory materials.
Refractory Bricks and Castables: Used in the production of refractory bricks and castables for high-temperature equipment such as glass melting furnaces, steel industrial furnace linings, and non-ferrous metal smelting furnaces, significantly extending the service life of furnace linings and improving corrosion resistance.
High-Temperature Coatings: As a component of high-temperature coatings, used to protect metal or ceramic surfaces from high-temperature oxidation and corrosion.
Plastics Industry
Zirconium silicate powder is mainly used as a filler in the plastics industry to improve the performance of plastic products. Specific applications include:
Epoxy Resin Formulations and Sealant Resins: Zirconium silicate powder can be added as a filler to epoxy resin formulations and sealant resins to enhance their strength, hardness, wear resistance, corrosion resistance, and dimensional stability.
Silicones and Vinyl Resins: In silicones and vinyl resins, zirconium silicate powder can also be used as a filler to improve the physical and mechanical properties of the materials, such as increasing hardness, wear resistance, and potentially enhancing flame retardancy.
General Resin Fillers: Due to its high refractive index, good chemical stability, and wear resistance, zirconium silicate powder is widely used as a filler in various resins. It can improve the fluidity and gloss of products, and reduce costs.
In summary, the application of zirconium silicate powder in the plastics industry primarily involves its use as a high-performance filler to impart superior physical and chemical properties to plastic products.
Paints and Inks
Zirconium silicate powder is widely used in paints and inks due to its high refractive index, good dispersibility, and chemical inertness.
White Pigment and Filler: As an efficient white pigment and filler, it can improve the hiding power, whiteness, and weather resistance of paints and inks.
Functional Coatings: In certain functional coatings, such as wear-resistant coatings and anti-corrosion coatings, zirconium silicate powder can be used as an enhancing component to improve the hardness and durability of the coating.
Other Emerging Applications
Nuclear Industry: Due to its small neutron absorption cross-section, zirconium silicate can be used as fuel cladding material or structural material in nuclear reactors.
Biomedical Materials: In the field of bioceramics and biocompatible coatings, zirconium silicate has good biocompatibility and can be used to manufacture dental materials, bone repair materials, etc.
Catalyst Carriers: As an inert carrier, it can be used to load active components and play a role in certain catalytic reactions.
