Alumina ware

HIGH ALUMINA LABWARE

• • • We offer the widest range of high alumina lab wares to satisfy your needs   in testing, analysis    and research.

    • The High Alumina Lab wares are made from 99.8% pure aluminum oxide. Highly resistant to       chemical attack, these wares are especially useful to chemist, material scientist, metallurgists    and others who are involved in high temperature work.

    • These ware are meant for use in oxidizing, reducing, hydrogen and carbonaceous atmospheres.

    • These wares are also suitable for use in glass melting especially borosilicate glass.

 SPECIAL FEATURES OF CRUCIBLES, BOATS, COMBUSTION TRAYS AND PLATES ARE AS FOLLOWS :-

•   Extreme Purity

•   High resistance to corrosion

•   Good thermal conductivity

•   Stability in oxidizing and reducing atmosphere

•   Ultra high vacuum resistance

•   Stability at high temperatures

•   Exceptional surface finish
