The results show that the size of molten titanium particles is smaller than that of HA particles, which is mainly caused by the formation of hollow structure due to aggregation of gaseous P2O5 and H2O within molten HA particles.
结果表明,经等离子熔融喷射入水后,钛粒子的尺寸小于HA粒子,主要原因之一是HA内形成了空心结构。
Fe3O4 microspheres with hollow structure were prepared by the glycol solvothermal method using FeCl3-6H2O and NH4Ac as reactants.
以FeCl3-6H2O和NH4Ac为反应物,乙二醇为溶剂热介质,制备了Fe3O4空心结构微球。
