Some factors affecting the chlorination of kaolinic clay.
Metall Trans 1977 Sep; 8B:435-441
Chlorination of small samples of kaolinic clay was studied by the Bureau of Mines by a continuous weighing technique. The effects of nacl additions, prior contact with sicl4 vapor, and the form of the reductant were qualitatively examined. Optimal chlorination of clay samples weighing less than 0.2 G was achieved in a fast-moving stream of CO and cl2 such that 90 pct of the aluminum and <5 pct of the silicon were reacted in 55 min at 625 deg c when 1 part nacl was added to 10 parts clay. Similar results were obtained in about 15 min at 750 deg c using chlorine gas with a mixture of 10 parts clay, 2 parts charcoal, and 1 part nacl.
