Microwave-assisted seed preparation for producing easily phase-transformed anatase to rutile

摘要: Titanium dioxide, as one of the most important optical materials, is usually manufactured by hydrolysis titanyl salts, in which seeds are a key to affect product properties. In sulfate process, normally leads anatase then converted rutile high-temperature calcination with help crystal transforming agent. this work, initial were prepared through microwave heating and introduced dilute solution. The results showed that had narrower particle size distribution compared traditional processes, it was much more easily under low-temperature absence effects on seed preparation conditions evaluated, kinetic behavior also studied.
