Summary: | The invention relates to a preparation method of lacunaris carbon matrix-ceramics composite material, which is characterized by: taking the waste of processed bamboo filings as raw material, adopting phosphoric acid to infuse, dry, bake, grind and sift out to obtain active bamboo charcoal powder; taking silica sol and trihydrate alumina to prepare antioxidant collosol; taking bamboo charcoal power and kaoline which are mixed with SOi2-A12O3 collosol and millet to blend into a mud pie to form dry body which is imbedded into a chark and is put in a ceramic crucible. The carbon matrix-ceramics composite material is obtained by being baked at the temperature of 900 to 1100 DEG C. |
