Product Introduction
Heavy calcium carbonate , produced by milling high-purity natural calcite, marble, or limestone, is a versatile and cost-effective inorganic filler powder. It is distinguished by its high chemical purity, strong inertness, excellent chemical resistance, and remarkable thermal stability (stable under 400°C). Additional advantages include high brightness, low oil absorption, low refractive index, soft texture, absence of crystal water, low hardness (resulting in low abrasion), non-toxicity, odorlessness, and superior dispersibility. These properties make it a preferred material for a wide range of industrial applications, including rubber, plastics, paints, water-based coatings, paper, concrete, and fire-resistant building materials.

Our high-purity diatomaceous earth, sourced from premium deposits, boasts excellent adsorption, filtration & thermal stability. Ideal for water treatment, food processing, agriculture & industrial applications. Safe, eco-friendly & cost-effective—delivers reliable performance for your professional needs.
Featuring long glow time, lightweight with high strength, wear and weather resistance, safety and environmental protection, and easy installation, resin-based luminous stones support customization of specific sizes, colors and luminous intensity according to project requirements. They are extensively used in luminous walkways/paths, garden decoration, feature walls, safety indication and guidance, artistic decoration, and lighting for parks, river banks and bridges.
High-quality kaolin undergoes calcination at high temperatures, leading to a series of physical and chemical transformations. During this process, it becomes dehydrated and crystallized, while volatile substances such as fluorine are removed. After cooling, the resulting calcined kaolin features high silica content, excellent whiteness, strong oil absorption, and high hardness.
This product is widely used across various industries, including ceramics, paper manufacturing, wall and floor tiles, rubber, and industrial coatings.
As functional decorative materials, glass-based luminous stones are crafted by fusing high-quality rare earth long-lasting luminous materials with glass substrates using special processes (such as high-temperature sintering or melting). They preserve glass’s crystal-clear appearance and hard texture, while being granted the distinctive property of self-luminating after dark—showcasing a clear, cool, and highly contemporary optical effect. They are extensively utilized in garden road paving, wall guidance signs, safety warning lines, water feature design, kitchen countertops, bathroom walls, and lobby feature walls.
Hollow glass microspheres—lightweight, spherical particles with a smooth, reflective surface—are mainly made of alkali-lime borosilicate glass. They integrate unique properties: low density, high strength, low thermal conductivity, top-tier electrical insulation, temperature resistance, chemical stability, and excellent fluidity. These versatile microspheres find wide application in adhesives, corrosion-resistant & insulating coatings, construction materials, rubber, synthetic wood, oilfield cements, and lightweight automotive composites.
Ordinary quartz powder effectively used as a filtration media for water treatment and as cost-efficient foundry sand in metalcasting. Reliable performance with 99% SiO₂.
Sintered colored sand, also known as high-temperature sintered colored sand or ceramic colored sand, is a high-end decorative material that uses a high-temperature ceramic sintering process to color selected quartz sand. Its core lies in using high temperatures (usually above 800℃) to fuse inorganic ceramic glazes with the surface of the quartz sand, forming a strong and dense colored ceramic layer.
High-quality kaolin undergoes physical and chemical changes through high-temperature calcination, dehydrating and crystallizing to lose substances like fluorine. After cooling, calcined kaolin is formed, which has high silicon content, good whiteness, strong oil absorption and high hardness. It is widely used in ceramics, papermaking, wall tiles, floor tiles, rubber, chemical coatings and other fields.
