在行星式磨机中以高加速度研磨获得纳米结构的β-赛隆前体粉末。初始氮化物/氧化物的各种混合物已被制备为低取代度（0.4-1.0z）的β-赛隆前体，并在加速度为28g的行星式研磨机（TTD，俄罗斯）中用氧化锆或氮化硅球研磨不同的时间（30-45分钟）。所得粉末显示出不同程度的晶格变形：较小的微晶、位错、凹凸不平的表面。晶格破坏的程度受到研磨时间和研磨介质的影响，然而不同的混合物成分表现出不同的变形敏感性。
Nano-structured β-sialon precursor powders were obtained as a result of milling in a planetary mill with a high acceleration. Various mixtures of initial nitrides/oxides have been prepared as β-sialon precursor with low (0.4-1.0z) substitution and were milled in a planetary mill of acceleration 28g (TTD, Russia) with zirconia or silicon nitride balls for a various times (30-45 min). The resultant powder showed various extents of crystalline lattice deformation: smaller crystallites, dislocations, bumpy surface. The degree of lattice destruction was influenced by the milling time and grinding media, however various mixture components showed diverse susceptibility to deformation.
