查询词典 rutile

In this paper, the technical conditions of preparing TiO2 ultrafine particle used as photocatalyst by Radio Frequency Plasma Chemical Vapor Deposition is studied, then suggest some methods of controlling the size and crystal type of TiO2 particles. And with the existent equipment prepare TiO2 particle taking on varies size by controlling the flow velocity of Ar as loading gaseity in the system of TiCl4+O2. By characterizing we know the particle prepared is the mix type of rutile and anatase.
