Abstract

本发明涉及一种球形或角形粉体填料的制备方法，提供包括T单位的球形或角形硅氧烷，其中，T单位＝R1SiO3‑，R1为氢原子或可独立选择的碳原子1至18的有机基；以及在惰性气体氛围或大气氛围条件下，对该球形或角形硅氧烷进行热处理，热处理温度为250度以上至650度以下，以使得球形或角形硅氧烷中的硅羟基发生缩合以得到球形或角形粉体填料，在该球形或角形粉体填料的T单位中，不含羟基的单位在总单位中的含量≥95％，含有一个羟基的单位在总单位中的含量≤5％。本发明还提供一种根据上述的制备方法得到的球形或角形粉体填料。本发明又提供一种根据上述的球形或角形粉体填料的应用。本发明提供的球形或角形粉体填料具有低诱电率，低吸水率和低放射性。
