Description
3 фосфорной кислоты .путем смешени кислоты с К1ремнийсодерж1ащим соединением и последующего .нагреванИ до 70-100°С, отличающийс тем, что, с целью упрощени способа. фосфорную кислоту предварительно упарива-5 ют до содержани 45-54% РзОб, з,атем сме4 шивают с двуокисью кремни и выдерживают 1 - 4 час. 2. Способ по -п. 1, отличающийс тем, что двуокись кремни ввод т ,в виде кислоторастзоримых силикатов, например трепела, метасил-икатав -кальци и магни , -каолтена.3 phosphoric acid. By mixing the acid with a K1-containing compound and then heating to 70-100 ° C, characterized in that, in order to simplify the process. the phosphoric acid is preliminarily evaporated to a content of 45–54% PcOb, 3, then mixed with silicon dioxide and incubated for 1–4 hours. 2. Method p. 1, characterized in that silicon dioxide is introduced, in the form of acid-soluble silicates, for example, tripoli, metasil-ikatav-calcium and magnesium, -caoltene.
