THE CONSISTANT RECYCLING OF PHOSPHATES AND SULFATES BY GAS-REDUCING METHOD WITH OBTAINING THE SULFIDES OF PHOSPHORUS
Journal Title: Молодий вчений - Year 2018, Vol 3, Issue 55
Abstract
The conditions of getting sulfides of phosphorus by calcium of phosphorus and sodium of sulfates mixture reducing by hydrogen, methane, carbon (II) oxide has been investigated. It has been established, that during reducing by methane or carbon (II) oxide within the temperature range 800–1000 K the sulfides of phosphorus synthesis and, above all things, Р4S3, Р4S10 is possible. The phosphorus sulfides can disintegrate into phosphorus and sulfur with subsequent temperature rising. Because of the processing of alunite phosphate system by gas-recovering method, the sulfides of phosphorus could be obtained. Aluminates of alkaline metals and alkaline soil metals – in solid phase. The proposal methods of recycling of phosphates and sulfates by gas-reducing method allows to simplify the technology of obtaining sulfides of phosphorus and to reduce the production cost price.
