| 摘 要： | 利用高钛高炉水淬渣和废玻璃粉为基础原料,以CaCO_3为发泡剂,Na2B4O7·10H_2O为助熔剂,Na_3PO_4·12H_2O为稳泡剂,通过"一步法"烧结制备微晶泡沫玻璃,研究了La_2O_3的添加对微晶泡沫玻璃物相、结构及性能的影响。结果表明,添加La_2O_3对晶相种类改变不明显,但会提高晶化程度。随着La_2O_3添加量由0%(质量分数,下同)增至1.5%,微晶泡沫玻璃的气孔孔径减小,晶粒由粒状变为短棒状,微晶泡沫玻璃的体积密度、抗压强度升高,气孔率、吸水率和导热系数降低。La_2O_3添加量继续由1.5%增至3.5%,微晶泡沫玻璃的气孔孔径增大,晶粒尺寸逐渐变小直至呈现无规则形状,微晶泡沫玻璃的体积密度、抗压强度降低,气孔率、吸水率和导热系数升高。当La_2O_3添加量为1.5%时,所制得的微晶泡沫玻璃的综合性能最佳。
