use of a grafitisierten, grafitglühofen at temperatures above 2000°c used as insulating material composition

摘要

The material is a mixt. contg. by wt. (a) 85-95% coke contg. over 90 vol. % of size 0.5-2 mm and below 10 vol.% of sixe 2-10 mm; plus (b) 5-15 wt.% wood shavings. After the material has been subjected to heat treatment at min. 2000 degrees C during the graphitisation of other prods., the material (a,be is pref. used as reducing agent, esp. in the nonferrous metals industry. After use in a graphitising furnace for the thermal insulation of other prods. (e.g. electrodes), the material (a,b) has high reactivity used e.g. for winning TiCl4 from Ti slags.
