PbO对泡沫玻璃性能影响的研究(英文)

STUDY OF PbO EFFECTS ON THE PROPERTIES OF FOAM GLASS

以废阴极射线管颈玻璃和氧化铅为主要原料,加入一定量的碳化硅、氟化铅、三氧化二铁、氧化铋,采用烧结法制备高密度泡沫玻璃,通过XRD、SEM等分析手段对泡沫玻璃的性能进行了研究.结果表明,发泡温度越高,制品密度越小;随PbO加入量的增加,发泡温度逐渐降低,密度和强度逐渐增大.试样在发泡温度810℃下保温30 min,产生了PbFeO2F、Pb、PbO等3种针状晶体,试样力学性能提高.

Abstract ： The high density tubes neck glass and PbO Bi2 O3. The properties of h aste cathode ray PbF2 , Fe2 O3 , XRD and SEM. The results show that the higher the foaming temperature, the lower the density. With the addition of PbO, the foaming temperature gradually decreases density and intensity gradually increasing. There are three needle-like phases PbFeO,F,Pb and PbO, to improve the me- chanical properties of the sample, which holding 30 min under the foaming temperature 810 ℃.
