| 摘 要： | 认为碎粒烧结法玻璃陶瓷的气孔率主要由玻璃液的澄清、粒度级配、杂质、烧成制度和化学组成决定。采用严格合理的澄清制度,以酸洗等方式剔除杂质或予以掺杂,建立适宜的烧结模型和碎粒紧密堆积所要求的粒度级配,优化配方,加人一定的Na2O等助熔剂,可显著减轻玻璃陶瓷的气孔率。

| Abstract: | The porosity of sintering glass -- ceramics is mainly determined by the following factors:melt clearing, distribution of different grain size levels, impurities, sintering model and chemicalcompositions. The porosity can be demilished greatly by restrict melt clearing, raw material acidleaching, ingredient adding, best sintering model and optimum combination of grain grade, chosingbest description and adding Na2O into it at suitable content. |
