Preparation method of high dispersion cuprous oxide

Abstract

The application provides a preparation method of high-dispersion cuprous oxide, wherein copper oxide particles are added into a sulfite solution, put into a sealed reaction kettle, stirred, heated to a temperature of 100-150 DEG C, then slowly added with an acid solution so that the pH of the end point is 7.5-8.5, the time for adding the acid solution is 1-3h, after the acid solution is added, the stirring reaction is continuously carried out for 30-60min, then cooled, filtered, washed and dried to obtain the cuprous oxide particles. The copper oxide particles are obtained by high-temperature hydrothermal method, based on copper ammonia complex ions, ammonia is gradually volatilized at high temperature, copper ions are gradually dissociated, then hydrolysis is carried out to obtain the copper oxide particles, the consistency and dispersity of the particles are high, then the particles are used as a basis to be reduced in a high-temperature aqueous solution environment to obtain the cuprous oxide particles, so the dispersity and consistency are high, and the copper smelting furnace soot is used as a raw material, so the cost can be greatly reduced.
