The High Alumina Crucible from Hofmann, a ZED certified leader in Wear Resistant Technologies since 1989, is engineered for demanding industrial applications requiring extreme durability and high-temperature resistance. Made from CERATUFF high alumina ceramic, these crucibles offer superior wear resistance, excellent mechanical strength, and outstanding corrosion resistance. Manufactured using advanced slip casting of ALCOA alumina and sintered to achieve a high density of 3.85 gm/cc, Hofmann's crucibles maintain dimensional tolerances under 2 mm, ensuring precise fit and usability. With the ability to withstand thermal shocks up to 150°C per hour and operate at maximum temperatures of 1750°C, these crucibles are ideal for laboratories and industries engaged in metallurgy, materials processing, ceramics, and chemical processing. The fine grain size of 2 to 4 microns contributes to enhanced strength and thermal stability, making these crucibles an excellent choice for high temperature melting, heat treatment, and chemical analysis tasks. Trusted by marquee clients such as Tata Power, JSW Steel, and NTPC, Hofmann’s High Alumina Crucible offers reliable performance and longevity in harsh industrial environments.
