Product details
The polycrystalline graphite shield plays a protective role in the polycrystalline ingot furnace. It is a two-layer composite structure, one layer is an isostatically pressed graphite material plate for supporting the crucible, and the other layer is a graphite carbon felt material for heat preservation. board.
Polycrystalline graphite shield is an inorganic non-metallic material, but because of its good thermal and electrical conductivity, low coefficient of thermal expansion, high melting point and chemical stability, it makes it important in engineering applications. Value. Graphite has good corrosion resistance and does not react with any organic compounds.
Graphite is a kind of high temperature resistant material. Graphite will not melt at high temperature. Graphite also has good thermal shock resistance. Graphite has good self-lubricating properties.
Graphite shields increase the oxidation rate with the increase of temperature due to the graphite material, so measures should be taken to avoid oxidation during the use.
