Abstract
The invention relates to a titanate optical filming material for glass, plastics and crystals. The prior optical filming material adopts a non-uniform physical mixing, thus affecting film quality. The invention adopts a chemical synthesis method. The titanate is prepared in solution and subjected to heat treatment in reducing atmosphere or vacuum atmosphere to obtain granular, flaky or blocky optical filming material. The obtained material realizes a mixing of a molecular and an atomic grade, and has the advantages of good uniformity and high quality of film.
Description
Affiliated technical field
The present invention relates to a class evaporation optical filming material, as the Coating Materials that is applicable to glass, plastics and other materials, the maximum characteristics of this material are chemosynthesis under liquid phase, reach molecule, atom level mixing, mixing uniformity is good, and after high-temperature heat treatment under reducing atmosphere or the vacuum condition, discharge quantity is suitable, evaporation is even, is the optical filming material of a class excellent performance.
Background technology
All kinds of composite optical Coating Materials of widespread use at present, mainly form by two or more oxide physical mixed, because the restriction of physical mixed particle size (being generally micron order), hybrid mode, make to mix between the various elements and have unevenness, the sintering temperature of compound, prefusing temperature and evaporating temperature height, to the requirement height of equipment, and the performance of plated film rear film produced certain harmful effect.There is the patent of some this respects the home and abroad, and major part all concentrates on the physical mixed level.
Summary of the invention
In order to overcome the physical mixed defective of existing coating materials, the present invention proposes the new method of the synthetic compound coating materials of a kind of liquid phase, mainly comprise the method for liquid phase synthesizing titanates such as the alkali formula precipitation method, oxalate precipitation method and hydro-thermal method.Its chemical raw material adopts soluble-salt and the titanium liquid of high-purity R, and precipitation generates precipitation under the effect of alkali or acid, obtains above-mentioned titanate after the thermal treatment.It consists of RxTiyOz, wherein R comprises strontium (Sr), lanthanum (La), praseodymium (Pu), cerium (Ce), zirconium (Zr), hafnium (Hf), tantalum (Ta) and their potpourri, x=0.01-100, y=0.01-100, z=0.01-100, x, y, z are nonstoichiometry unit'ss (molecule number ratio) of potpourri.These titanates obtain required material after reducing atmosphere or vacuum heat.
The titanate of the present invention's preparation, its granularity is a nanoscale, and has passed through the mixing of molecule, atomic level in solution, combines closely between the variant element, active increasing, sintering temperature reduces, and solid phase reaction is abundant; The prefusing temperature of material and evaporation temperature are all hanged down 200-300 ℃ than the material of physical mixed, and evaporation rear film good uniformity absorbs little.It is the optical filming material of a class excellent performance.
