研究了纳米结构β-硅烷前驱体对陶瓷烧结性能的影响。将取代度为0.4z的β-赛隆前驱体标准混合物在行星磨机中以28g的加速度活化30min。在行星磨机中活化导致粉末颗粒的晶粒尺寸减小和晶格明显缺陷。烧结实验在1450 ~ 1600℃的粉末床中进行。烧结体的相对密度达到97%。在1500℃下进行无压烧结制备纳米结构材料。结果表明，高活化度是制备致密陶瓷的必要条件。
The results on the effect of nanostructured β-sialon precursor on the sintering and properties of the resultant ceramics are presented. The standard mixture of β-sialon precursor with 0.4z substitution degree was activated for 30 min in a planetary mill with an acceleration of 28g. Activation in the planetary mill resulted in diminution of the crystallite size and significant imperfection of the crystal lattice of the powder particles. The sintering experiments were performed at 1450-1600 °C in a powder bed. The relative density of the sintered bodies achieved the value of 97 %. The nanostructured material was produced after pressureless sintering at 1500 °C. It is concluded that high activation degree of the powders is necessary to obtain fully dense ceramics.
