摘要
研究了超细ZrO2粉体注凝成型过程中固相含量对料浆粘度、生坯强度和烧结材料密度等的影响。在固相含量50vol％～54vol％的范围内，随着固相量的增加，料浆悬浮体的粘度明显提高，成型坯体的均匀性下降，生坯强度出现极值，烧结材料的密度逐渐降低，固相含量以50vol％～52vol％为宜。
Effects of solid loading on slurry viscosity, bending strength of green body, and density of sintered materials in super-fine ZrO2 powder gelcasting were studied. With the increase of solid loading from 50vol% to 54vol%, viscosity of ZrO2 suspension increases distinctly, uniformity of green body prepared in gelcasting decreases, bending strength of green body takes on a maximum, and density of sintered materials reduces gradually. Therefore the optimum solid loading is 50vol%～52vol%.
