Description

Diaspore CAS NO 14457-84-2 is a naturally occurring aluminum oxide hydroxide mineral with the chemical formula AlO(OH). This high-purity industrial mineral is a critical raw material valued for its high alumina content and refractory properties. It is essential for manufacturers in the ceramics, refractory, and abrasives industries seeking consistent quality and reliable supply for high-temperature applications.

Application

• Refractory Production: A key component in the manufacture of high-alumina refractories, bricks, and castables for furnaces, kilns, and reactors due to its excellent thermal stability.
• Advanced Ceramics: Used as a precursor material in the production of technical ceramics, including spark plugs, wear-resistant parts, and electronic substrates.
• Abrasive Manufacturing: Serves as a raw material for fused alumina abrasives used in grinding wheels, sandpaper, and blasting media.
• Glass & Fiberglass Industry: Acts as a source of alumina to modify the chemical resistance, viscosity, and mechanical strength of glass and fiberglass batches.
• Catalyst & Catalyst Support: Utilized as a support material or precursor for catalysts in various chemical processes, including petroleum refining.
• Flame Retardant Filler: Incorporated into polymers and composites as a non-halogenated flame retardant additive that enhances fire resistance.
• Precursor for Aluminum Chemicals: A source material for the synthesis of various aluminum compounds, including aluminum sulfate and polyaluminum chloride (PAC).
