Graphitblöcke

Graphite blocks have good resistance to thermal shock, oxidation and corrosion, and have suitable resistivity and homogenous structure. They have been used extensively in industries like solar, foundry, chemicals, electronics, ferrous metals, high-temp, processing, ceramics and refractory. The specific applications include: Casting Molds ;Resistance Heating Elements ;Channels Parts For Heat Exchangers ;Susceptors For Induction Furnace ;Furnace Linings ;Head Electrodes For Acheson Furnace ;Anodes For Metals Electrolysis ;Boats And Trays For Sintering ;Heat Shields And Covers For Pulling Of Monocrystalline siliconGrade HTK1Typical Properties at Room TemperatureEnglish UnitMetric UnitBulk Density99 lbs/ft31.60 g/cm3Max.
