Chengdu Artech Specialty Graphite Co.,Ltd is one of the leading China graphite hot zone for poly silicon manufacturers and also a professional graphite hot zone for poly silicon supplier,Website: , welcome to import products from our factory.Product name: Graphite hot zone for polysilicon             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.Graphite hot zone have high thermal stability.Graphite does not melt but sublimes at about 3627 ℃ .2.Graphite hot zone have good electric conductivity.As temperature rises, electrical conductivity increases. 3.Graphite hot zone have high thermal conductivity.The thermal conductivity of graphite is higher than that of many metals and falls with increasing of temperature. 4.Graphite hot zone can resist thermal shock. so rapid heating or cooling is not a problem.5.Graphite hot zone can resist corrosion.It can be widely used in acid based environments.6.The tensile,compressive and flexural strength of Graphite hot zone are very high.7.Graphite hot zone have high purity. Graphite can be purified to 20-30 ppm in block or less than 5 ppm for thefinished items.
