Chengdu Artech Specialty Graphite Co.,Ltd is one of the leading China carbon crucibles manufacturers and also a professional carbon crucibles supplier,Website: , welcome to import products from our factory.Product name: Carbon crucible             Material: high pure graphiteSize: customizeApplication: photovoltaic,electronics and semiconductor industriesDensity: 1.65-1.88 g/cm3Compressive strength: 30-240MpaFlexural strength:7-85MpaSpecific electrical resistance:6.5-15μΩmBrand Name: OEMMOQ: 1 pcsDelivery date: 20 daysPackage: Polywood or custom packageFunction:1.Carbon crucible have high thermal stability.Graphite does not melt but sublimes at about 3627 ℃ .2.Carbon crucible have good electric conductivity.As temperature rises, electrical conductivity increases. 3.Carbon crucible have high thermal conductivity.The thermal conductivity of graphite is higher than that of manymetals and falls with increasing of temperature. 4.Carbon crucible can resist thermal shock. so rapid heating or cooling is not a problem.5.Carbon crucible can resist corrosion.It can be widely used in acid based environments.6.The tensile,compressive and flexural strength of Carbon crucible are very high.7.Carbon crucible have high purity. Graphite can be purified to 20-30 ppm in block or less than 5 ppm for thefinished items.
