Applications

I. Refractory Materials (Core Application)

- Core linings for steelmaking furnaces: Magnesia-carbon bricks, magnesia-alumina spinel bricks and large crystal magnesia bricks applied to converters, electric arc furnaces, slag lines of refining ladles and continuous casting slide gates. They feature strong resistance to erosion and scouring by molten steel and slag with a long service life.

- Glass kilns / Cement kilns: Checker bricks in regenerators, furnace arches and feed channels of glass kilns; burning zones and furnace mouth guards of cement kilns. They withstand temperatures above 1800°C, resist alkali erosion and maintain stable thermal shock performance.

- Unshaped refractory materials: Ramming mixes, gunning mixes, castables and dry mixes for lining and repairing ladles, electric arc furnaces and induction furnaces, featuring high bulk density and spalling resistance.

- Special metallurgical furnaces: Linings and hearths of vacuum induction furnaces, electric arc furnaces and non-ferrous metal smelting furnaces, resistant to molten metals, low in impurities and high in electrical insulation.

II. High-Temperature Electrical Insulation (Electronics & Electrical Engineering)

- High-temperature insulating fillers: Thermocouple protection tubes, insulating layers of resistance furnaces and muffle furnaces, heating element fillers and electronic packaging insulation, featuring high temperature resistance, superior insulation, low power loss and anti-aging performance.

- Nuclear & military insulation: High-temperature insulating layers, shielding materials and control rod guide tubes of nuclear reactors; special military ceramics, radar radomes and missile components, characterized by high purity, low chlorine content, excellent thermal stability and radiation resistance.

- Refractory ceramics / Crucibles: Magnesia crucibles, furnace liners, high-temperature sleeves and ceramic substrates for laboratory and industrial high-temperature melting and sintering, non-sticky to metals, high temperature resistant and corrosion resistant.

III. Ceramics and Functional Materials

- Electronic ceramics / Substrates: Sintering aids and fillers for alumina ceramics, aluminum nitride ceramics and 5G radio frequency ceramics to improve density, thermal conductivity, insulation and mechanical strength.

- Wear-resistant / Friction materials: Brake pads, clutch plates and industrial wear liners, featuring high hardness, wear resistance, thermal stability and no softening at high temperatures.

- Flame retardants / Fillers: CPE cables, EVA photovoltaic films and PVC flame retardant materials, high-purity halogen-free, smoke-suppressing and thermally stable, serving as a substitute for halogen-based flame retardants.

IV. Metallurgy / Chemical Industry / Environmental Protection

- High-grade desulfurization and dephosphorization agents: High-purity agents for desulfurization and dephosphorization of molten steel to enhance steel purity with low impurities and prevent secondary pollution.

- Chemical carriers / Fillers: Fillers for high-temperature reactors and catalyst carriers, and dehydrating agents for concentrated nitric acid, featuring high temperature resistance, corrosion resistance and chemical inertness.

- Raw material for magnesium salts: Used to produce high-purity magnesium sulfate, magnesium chloride and magnesium nitrate for pharmaceutical, food and electronic-grade magnesium salt manufacturing.
