Abstract:

一种多孔结构特征的导电硅藻土制备方法涉及材料领域。本发明步骤:取结晶四氯化锡,三氯化锑溶解在浓度为2mol/L的HCl溶液中;取硅藻土悬浮于水中形成悬浊液,加入HCl调节悬浊液为酸性,搅拌使其成为均匀悬浊液,控制反应温度在30~70℃,在1~4个小时内匀速滴加上述酸混合液,同时滴加NaOH溶液保持悬浊液pH值在0.5~3范围内;滴加结束后继续沉化0.5~2小时,使沉化完全;最后过滤并用蒸馏水洗涤除去Cl-,干燥,在500~900℃煅烧1~3小时;本发明采用化学共沉淀法通过在硅藻土基核上包覆Sb掺杂SnO2导电物质,制备出具有多孔结构的复合导电粉,所得材料电阻率可降14Ω·cm。
