Недостатком И31вестного способа вл етс невысокое качество готового -продукта, малый выход оо току, а также высока температура .процесса.A known method for producing titanium disilicide is an electrolysis of alkaline metal fluorosilicates of alkali metals with the addition of a titanium containing compound. The disadvantage of this well known method is the low quality of the finished product, low current output, and a high process temperature.
Предлагаетс способ чполучени дисилицида титана электролизом расплавленного фторсилцката щелочного металла с добавкой титансодержащего соединени и галогенидов щелочных металлов, причем составл ющие электролита берут в следующем соотнощении, вес. %;A method is proposed for obtaining titanium disilicide by electrolysis of molten alkali metal fluorosilicate with the addition of a titanium-containing compound and alkali metal halides, the electrolyte components being taken in the following ratio, wt. %;

Электролиз ведут в атмосфере инертного газа, на-прнмер аргона.Electrolysis is carried out in an inert gas atmosphere, on-argon.
выход готового продукта .по току до 70%, а также снижает у;пругость ларов тетрафторида кремни над расплавом, что улучщает антикоррозионное состо ние электролизера. При использовании окисных соединений титана, например Ti02, расплав перед электролизом отфильтровывают от частиц двуокиси кремни . Применение в качестве титансодержащего соединени Na2TiF6, позвол ет получать катодные осадки высокой частоты, легко поддающиес гидрообработке.the yield of the finished product is up to 70% current, and also reduces the melting point of silicon tetrafluoride over the melt, which improves the anticorrosion state of the electrolyzer. When using oxide compounds of titanium, for example, TiO2, the melt is filtered before electrolysis from silica particles. The use of Na2TiF6 as the titanium-containing compound allows to obtain high-frequency cathodic precipitations that are easily hydroprocessed.
