Pyrolytic graphite crucible: high purity, dense, andHigh temperature, strong acid and alkali corrosion resistance, easy washing and other characteristics, have been widely used in the pretreatment of minerals, building materials, glass and other samples.Compared with platinum, silver, nickel, corundum, quartz and other crucibles, it has the advantages of less impurities and low cost.Pyrolytic graphite is decompressed at high temperature (around 2000°C)PG crucible has high purity (connected with spectrally pure graphite In an inert atmosphere, hydrocarbons decompose and polymerize, producing Close), dense, low air permeability (same as glass), high resistance into huge aromatic hydrocarbons, which are then deposited on a high-purity graphite matrixhigh temperature, strong acid and alkali corrosion resistance, resistance to sudden cooling and sudden heat changes, easy to wash The surface of the material is obtained by dehydrogenation and recrystallization. Fifty Polyester and other advantages
