FIELD: silane production from natural quartzite.
SUBSTANCE: method for silane production includes interaction of silicium-containing compound (e.g. quartzite) with lithium hydride. Backing is carried out at 790-8200C followed by crushing of fusion cake. Fusion cake is placed on continuously renewed surface of moving ice plates made from distilled water. Claimed method is useful in production of high pure semiconductor silicium for electronic industry.
EFFECT: silane synthesis from economy raw materials; safe technology.
