Carbon or graphite article and method of making by impregnating with a lignin sulfonate complex |
摘要 |
In a process for producing carbon or graphite articles, baked carbonaceous articles are impregnated with an aqueous solution of lignin sulfonate complex prior to carbonization or graphitization. The carcinogenic effects of conventional impregnants are eliminated, and impregnation temperatures are lowered significantly.
