Metal oxide

Ceramic membranes are of particular interest in many industrial processes due to their ability to function under extreme conditions while maintaining their chemical and thermal stability. Major structural deficiencies under conventional fabrication approach are pin-holes and cracks, and the dramatic

The present study is concerned with the sulfidation treatment of metal reagents of Cu(OH)2, ZnO or Ni(OH)2 as a means of metal resources recovery. The sulfidation was conducted separately for each reagent by contacting the reagent with Na2S solution (S2– to Me2+ molar ratio of 1.5) for 1 h to 7 d. T
