In4Sn3O12 compound oxide particulate and its production method for solar radiation cover and application liquid and solar radiation cover membrane for solar radiation cover membrane formation and backing material for solar radiation cover

摘要

As it reacts with the raw materials mixed solution and the alkaline solution which contain the tin compound and the indium compound while agitating continuously, making mature, washing process and the aforementioned deposit which obtain the deposit with decantation, drying and of process and under mixed gas atmosphere of the inert gas or the inert gas and the restoration characteristic gas which obtain hydroxide or the hydrate powder which consists of indium and tin calcining this hydroxide or the hydrate powder above the 1200C with the method of possessing with the process which obtains the In₄ Sn₃ O₁₂ compound oxide particulate in comparison with former ITO and the like at the same time cheapness produce simplyBecomes possible, below even primary particle diameter 400nm, the powder body color L at the same time in L ^*a*b* color coordinate system ^* 30 - 70, a ^* -9.0 - -0.1 and b ^{* the} -15.0 - 4.0 can obtain the In₄ Sn₃ O₁₂ compound oxide particulate for solar radiation cover which is.
