To the mechanism of influence of an alternating electromagnetic field on crystallization process of oxide refractory melts

Electromagnetic effect during crystallization of melts various materials (metallic, salt, slag, oxide) is able to change significantly its macro- and microstructure improve physical technical characteristics. There are many hypotheses about the mechanism electromagnetic field on structure metals. limited studies electric, magnetic temperature fields non-metallic crystals in complex halide oxide systems. The available works this topic fragmentary aimed only at solving utilitarian problem obtaining crystals. No high-temperature refractory final characteristics have been found known scientific literature. In paper, for first time, based analysis hypotheses, new study mineral composition, structure-sensitive structural units melts, hypothesis alternating crystallizing from example forsterite, forsterite-chromite corundum refractories has put forward. most probable an castings periodically orienting intensifying migration melt action.
