Abstract： |
A low temperature process of preparing nanometer rutile phase titania includes compounding reaction solution A with tetrabutyl titanate and ethanol, compounding reaction solution B with deionized water and nitric acid, adding solution A slowly into solution B and stirring to form a uniform solution, further stirring at room temperature for complete hydrolysis to become a sol, maintaining the sol at 30-60 deg.C for 5-20 hr to convert into gel gradually, and then becoming powder, that is the requried nanometer rutile phase titania. The process of the present inventino is simple, easy to operate, low in power preparing temperature, saving in power, pollution-less, high in product purity and homogeneous in product particle. |
