Graphite material has: high temperature resistance, oxidation resistance,chemical stability, good self lubrication. Its texture is hard and brittle, itsplasticity is not good, and its impact resistance is poor.
Because graphite crucible has high temperature resistance, high meltingpoint and other characteristics, it is very commonly used.
1.Easy to polish; Because the cutting resistance of graphite is only 1 / 5 of that of copper, itis easier to grind and polish;
1.excellent heat resistance and cold resistance. The physical properties offlexible graphite can be applied to about 600 ℃ in air, from ultra low temperature of -270 C to high temperature of 3650 ( in non oxidation gas);
