Description

Chrysoberyl is a beryllium aluminate mineral prized for its exceptional hardness, chemical stability, and unique optical properties. Its primary commercial value lies in its gem varieties, alexandrite and cat's eye, but its industrial-grade forms are critical for specialized high-performance applications. This material is essential for manufacturers in the advanced ceramics, optics, and abrasives industries seeking durable, heat-resistant components. We supply high-purity Chrysoberyl CAS NO 1304-50-3 to meet the stringent demands of global industrial and research sectors.

Application

• Advanced Ceramics & Refractories: Used as a key component in high-temperature, wear-resistant ceramics for furnace linings, crucibles, and thermal barrier coatings.
• Optical Components: Serves as a substrate or material for specialized lenses, windows, and laser components due to its excellent transparency in certain wavelengths and durability.
• Abrasive & Polishing Media: Utilized in powdered form for precision lapping and polishing of hard materials like metals, glass, and other ceramics.
• Gemstone & Jewelry Manufacturing: Supplied as rough or cut stones for the production of the highly valued alexandrite and cat's eye gemstones.
• Research & Development: Employed in material science research for studying high-hardness compounds, solid-state physics, and novel ceramic matrix composites.
• Defense & Aerospace: Incorporated into components requiring a combination of hardness, thermal stability, and transparency for sensors and protective systems.
