Article ID: 1003-6326(2005)05-1156-05 Preparation of titanium dioxide/silver sulfate powder and its antibacterial activity PENG Bing(彭 兵), YUAN Chun(苑 春), CHAI Li-yuan(柴立元), WEI Shun.../silver sulfate were produced by heat-treatment of the metatitanic acid, as precursor, into which the silver nitrate was added. The influences of heating temperature on the structure and composition......
) and oxygen particle pressure (1 MPa). Fig.5 shows that, with increasing the amount of sulfate, the leaching rate of zinc and the conversion of sulfur were increased. When the solid-to-liquid ratio was over 1...

1 indicates that the main phase in ZLR was zinc ferrite (ZnFe2O4), while lead sulfate (PbSO4), zinc silicate (Zn2SiO4), calcium sulfate (CaSO4), zinc sulfate (ZnSO4) and zinc sulfide (ZnS) were... converted into zinc sulfide by sulfidation roasting. In addition, the content of zinc in the form of sulfate, oxide and silicate also declined after sulfidation roasting, demonstrating that not only......
