透辉石微晶玻璃的低温烧结制备及性能表征
|
摘要
以废弃建筑玻璃为主体原料,将废玻璃粉、高岭土和氧化镁进行球磨混和,压制成型后直接烧结,在低温下成功制备出具有单一透辉石晶相结构的微晶玻璃。采用X射线衍射、场发射扫描电子显微镜等测试手段,研究了MgO加入量和烧结温度对微晶玻璃样品的晶相组成、显微结构及性能等的影响。结果表明:随着MgO加入量的增多以及烧结温度的升高,微晶玻璃的体积密度和抗弯强度均呈现先增大后减小的趋势。MgO加入量和烧结温度的提高可以有效促进透辉石晶相的析出。当MgO加入量为4%、975℃烧结2 h时所制备得到的透辉石微晶玻璃性能最好,其体积密度为2. 395 g·cm~(-3),抗折强度102. 1 MPa。
Glass-ceramics with single diopside crystal phase structure were successfully prepared at low temperature by sintering the green bodies into which the well-mixed powders by ball milling were pressed,where the mixtures were composed of the waste building glass powder,serving as the main raw material,kaolin and MgO. The effects of MgO content and sintering temperature on phase composition,microstructure and properties of as-prepared glass-ceramics were investigated by means of X-ray diffraction and field emission scanning electron microscopy. The results show that bulk density together with bending strength of glass-ceramics initially increased and then decreased with the increase of MgO content and sintering temperature. Increasing MgO adding amount and sintering temperature could effectively promote the formation of diopside phase. Diopside-based glass-ceramics prepared by 4 wt% MgO and sintered at 975 ℃ for 2 h showed the best properties,with bulk density of 2. 395 g·cm~(-3) and the bending strength of 102. 1 MPa.
