Description

Существовавший до насто щего вре . мени способ получени  (росфрра заключалс ,; в восстановлении фосфатов; при этом, однако, часть фосфора св зываетс  .железом, восстанавливаемым и железо-| содержащей соли фосфорной кислоты. В предлагаемом способе вытесн ют фос-фор из его соединени  с железом-фер- рофосфора посредством других веществ, /образующих с железом соединени , как-то сера, кремний и др. С технической точки . зрени  интерес представл ет в этом отношении кремний, поскольку получающийс  нри атом ферросилиций  вл етс  продукрок , имеющим на рынке посто нный спрос. Исследовани ми установлено, что из ffiep:рофосфора можно получить ввеДейием «ремни  ферросилиций с с(держанием от, .40- 500/0 кремни , приналичци менее , фосфора.

Способ получени  фосфора из феррофосфора , отличающийс  тем, что феррофосфор сплавл ют в электрической печи с кремнием или ферросилицием, содержащим высокий процент кремни , или же. с соответствующими количесткайн кремневой кислоты и углерода. тски Печат  к, и оила , 4ft .. - - , , . .., , . . -,.Existed before now. The method of preparation (rosphrr was to restore phosphates; however, part of the phosphorus is bound by iron, which is reduced and iron-containing phosphoric acid salt. In the proposed method, phosphorus is displaced from its compound with iron-fer- By means of other substances forming compounds with iron, such as sulfur, silicon, etc. From a technical point of view, silicon is of interest in this respect, since the resulting ferrosilicon atom is a continuous product that has a steady demand on the market. It has been established that ffiep: rophosphorus can be used to introduce ferrosilicon c-belts with (holding from, .40-500/0 silicon, less phosphorus. When administered, the process tends to obtain common products with a silicon content, 50, 75 or. To obtain, phos el lpl I-n.

With required amounts of silicon or ferrosilicon, containing a high percentage of silicon, or with an appropriate amount of silicic acid and carbon of the genus (eg coke), As a mixture to form a silicon - in a conventional electric furnace device provided with a fixture for collecting volatilized mi vapor; phosphorus. If necessary, the removal of phosphorus vapors from the space of the furnace can be accelerated by the introduction of neutral gases. Ferrosilicon is released periodically and continuously. The subject of the patent. A method of producing phosphorus from ferrophosphorus, characterized in that the ferrophosphorus is fused in an electric furnace with silicon or ferrosilicon containing a high percentage of silicon, or. with the corresponding quantity of silicic acid and carbon. tski Print to, and oila, 4ft .. - -,,. ..,, . - ,.
