Robuster Quartz Special Crucibles for Industrial Application

Series of crucibles for industrial level: RBS Non metal purity market. Such as zirconia alumina purity field. Industrial crucible is available in severe thermal shock and chemical corrosion situation. It can be used in phosphors, fluorescent, rare earth powder calcination and some metals and metal oxides smelt. Higher density 2.15g/cm3(normal fused silica ceramic 1.9g/cm3), higher strength no shrinkage at high temperature, which guarantee convenient and safe application. Excellent anti-thermal shock properties. Keep 1100? in 15 minutes and suddenly dip in cold water, no crack for 10 times cycle. Low porosity (<1%) ,Smoothly inner surface. High-purity material (>99.9999%SiO2). Good chemical stability. Inert to most acid, base, metal and metal oxide. Melting temperature at 1350?, Maximum temperature 1600?.
