Uxcell 30ml Corundum Alumina Crucible for Foundry Melting Casting Refining Alumina crucible (or corundum crucible, aluminum oxide >99%) feature highly resistant to chemical erosion. For use in reducing and oxidizing atmospheres and metals (such as molybdenum, platinum, rhodium, tungsten, and iridium). Heating too fast or uneven heating may crack the crucible. Slow down the heating rate is good for prolonging its lifespan.
