High Density Silicon Carbide Crucible for Smelting of Lead¹

Product Description Product DescriptionGraphite crucible can withstand the high temperature, and has good resistance to chemical erosions and thermal shock. Especiallycrucible is a container used to hold metal for melting in a furnace and it is needed to withstand the extreme temperatures encountered in melting metals. The crucible material must have a much higher melting point than that of the metal being melted and it must have good strength even when white hot.ContentDensityApparent porosityMax service tempSiC:1-40%        C:20-50%    Al2O3:2-45% SiO2:3-38%2.30 g/cm3≤30%1750° Product Parameters Table size of clay graphite crucibleNo.Height mmUpper OD mmBottom OD mm2#100905010#1731629510#17515011012#18015510520#24019013030#26021014530#30023717040#32527518570#35028019080#360300195100#380325225120#400347230150#435355255200#440420270250#510420300300#520435310400#690510320500#740540330500#700470450800#800700500Parameter index of crucibleSICCBULK DENSITYAPPARENT POROSITYModulous of RuptureREFRATORINESS≥ 40%≥ 35%≥2.2 G/CM3≤15%≥10Mpa1790oC      Detailed PhotosFeatures of  Isostatic Silicon Carbide/SiC/Graphite crucible  Excellent thermal stability and distortion resistance at high temperature.High mechanical strength at high temperature.Excellent thermal shock resistance.High thermal conductivity.Excellent oxidating resistance.Excellent corrosion resistance at high temperature.Excellent corrosion resistance against chemicals.High abrasion resistance.Application of silicon carbide graphite crucible: 1. Graphite crucible can be used for non-ferrous metal smelting and casting, dissolving gold or silver ornaments, analysis of special type steel, sintering hard metal.2. graphite crucible for smelting gold is specialized in melting gold in headgear and jewelryindustry. That requests graphite material has high density and purity, ablation-resistance, and it can be used many times. We can machine various crucibles accordingto customer's requirement.3. Machined from high pure graphite and widely used in the gold,silver,platinum and other noble metal's melting.If it's used in oxygen atmosphere,it wil start to be oxygenized when the temperature is higher than 700-800°c. If it's used in the protective atmosphere, it can stand more than 2000°c.4. widely used in such fields as industrial furnaces, mono-crystalline silicon machinery, mono-crystalline silicon machinery, electron, semi-conductor, metallurgy, oil, chemistry, textile, electrical machinery, electrical equipment, electrical furnace, traffic, communication industry, medicine, etc. Recommended Product Packaging & ShippingPackaging of refractory heat insulation ceramic fiber board: PE bag inside outer carton(930*630*230mm),finally make the wooden pallet(950*950mm 950*1000mm) or according to your requirementShipping :  delivery within 15 days after confirm the order.  Our Advantages  Our products are warranted to be free from defects in materials or workmanship for 6months from the date of purchase.
