摘要:
Suspensions and powders based on indium tin oxide are prepared by a method in which indium tin oxide precursors are precipitated from solutions in one or more solvents in the presence of one or more surface-modifying components, the solvent(s) are removed from the precipitate, which is then calcined, one or more surface-modifying components and one or more solvents are added, the mixture is comminuted or dispersed to form a suspension, and the liquid components are separated from the suspension to give a powder. The powder may be converted into a moulding by a shaping process. The materials prepared by this method are especially suitable as coating materials for use in microelectronics and optoelectronics.
