Industrial use
Many of the compounds of arsenic containing a deadly poison, often add ratsbane in herbicide, etc.. A conductor of electricity is used in a semiconductor. Compounds are commonly referred to as arsenide, often used in the manufacture of coatings, wallpaper and pottery.
Editing method
Carbon vapor reduction method
Three electric furnaces are assembled with a gasification section, a reaction section, and a precipitated section. The central reaction part is a quartz tube with an inner diameter of 20-25mm, which is loaded with charcoal discharged by vacuum heating. The two ends are blocked with quartz wool and placed arsenic trioxide in the quartz dish, and then put into the gasification section. The nitrogen is purified at the speed of 400-500mL/min. The temperature of the gasification section is kept at 400 C, the reaction section is 650 degrees C, the precipitation section is 350-400 degrees C, and the elemental arsenic is precipitated through the reaction about 1H, and then the finished product is made by distillation.
