The carbon graphite material prepared by the means of improving the oxidation resistance of the basic body materials and impregnated with phosphates had better oxidation resistance.
Their properties are better than those of metal-impregnatedgraphite sealing materials and their lifetime is increased by 4-6 times compared with the latter.
