Preparation of Antioxidant Graphite Electrode by ordinary carbon production process
Porous carbon and porous graphite blocks can be produced by a common carbon production process, except that a pore-forming agent is added to the ingredients, and the pore-forming agent volatilizes or decomposes to form pores during firing and graphitization. Commonly used pore-forming agents are sodium chloride, sodium fluoride, sawdust, etc., and the addition amount of the pore-forming agent and the particle size of the pore-forming agent are controlled to roughly control the porosity and pore diameter of the porous carbon and the porous graphite.
Preparation of Graphite Electrode by chemical vapor deposition
A carbon filter plate (porous carbon) is prepared by a chemical vapor deposition process using a carbon felt as a substrate. The porous carbon plate obtained by the method has a tensile strength of 43 MPa, a compressive strength of 105 - 130 MPa, and a porosity of 20 to 30. %, mechanical strength ratio. The material produced by the pore forming method of the conventional carbon production process pore-forming agent is much larger. It can filter particles of > 5 pm and can be used below 5001. It is resistant to corrosion by strong acid and alkali and fluoride hot solution. For chemical separation of niobium in Ni-based superalloys.
