Abstract:
Self-propagating high temperature synthesis processes are one of the highly productive and economically reasonable methods for the metallurgy industry. The latest stage in the production of advance ceramic powders by SHS method was the leaching process, in which the elimination of several impurities such as MgO and magnesium borates from SHS product was took place by using concentrated hydrochloric acid solutions. Leaching of SHS product resulted in the production of high purity advance ceramic powders together with Mg and B containing spent solution. In this study, removal of zirconium, magnesium and boron compounds from relevant chloride containing spent solutions was aimed. The effects of chemical reagents, pH of the solution on the precipitation efficiency were investigated in the study. Chemical analysis and the characterization of solid phases by using x-ray diffraction and chemical analysis were the latest stage.
