Abstract
A process for preparing nano-class yttrium oxide powder features that under the existance of surfactant, the solution of yttrium ions reacts on the alkaline solution under normal temp. and pressure. Its advantages are fine granularity (10-60 nm), high dispersity and low cost.
Description
technical field [0001] The invention relates to a method for manufacturing nanometer materials, in particular to a method for manufacturing nanometer yttrium oxide powder. Background technique [0002] Yttrium oxide is mainly used in the manufacture of magnetic materials for microwaves and single crystals of important military materials; it can also be used as optical glass, ceramic material additives, high-brightness phosphors for large-screen TVs and other kinescope coatings, and is also used as film capacitors and Special refractory materials, as well as high-pressure mercury lamps, lasers, magnetic bubble materials for storage components, etc. The particle size of yttrium oxide powder material directly affects the quality, precision and grade of its downstream products. The particle size of yttrium oxide powder produced by the current technology can only reach about 0.5 μm, which is far from meeting the demand for high-quality products. The Chinese...
