Eduscope India is a leading Crucibles, Conical Form, High Alumina
Quick Answer: the Crucibles, Conical Form, High Alumina are unglazed, 99.7% pure alumina crucibles rated for use up to 1750°C, built for chemists and metallurgists who need contamination-free results in high-temperature work — a specialty crucible tongs India lab technicians reserve for jobs an ordinary porcelain or quartz crucible can't survive.
High alumina ware is highly refractory and works in both reducing and oxidizing atmospheres, staying inert in hydrogen and carbonaceous environments while resisting alkalies and other fluxes that would attack lesser ceramics. As a chemistry lab instruments supplier, EduScope India stocks this grade for glass melting work, including borosilicate glass, and for use alongside refractory metals such as molybdenum, platinum, rhodium, tungsten, tantalum and iridium.
