摘要
制备钇稳定氧化锆纳米粉体,XRD测定表明Y2O3掺来对ZrO3晶型未产生重大影响。作为冷气溶胶灭火剂的主要材料进行其对一元醇的阻爆和吸附实验,结果表明:ZrO2(Y2O3)纳米粉体对燃烧反应具有抑制作用,对一元醇具有阻爆和消爆作用,其作用的机理不是ZrO2(Y2O3)对一元醇的吸附,而是ZrO2(Y2O3)对燃烧链反应传递物的捕获。
ZrO2 （Y2O3 ） nanopowder was made and the XRD test showed that the Y2O3 has no significant influence on the poly- morphs of ZrO2. A series experiments have been done to study the effects of ZrO2 , a new extinguishing agent in cold aerosol, on abating explosion and the adsorption of monohydric alco- hols. According to the results, ZrO2 （Y2O3） nanopowder could inhibit combustion reaction and could retard and abate explosion caused by monohydric alcohols. The mechanism of its reaction is not the adsorption of monohydric alcohols by ZrO2 （Y2O3 ）, but its capture of additives in combustion chain reactions.
