Abstract
Inventia se refera la tehnologia de obtinere a materialelor oxidice multicomponente, in special, laun procedeu de obtinere a galatului de zinc nanostructurat, care poate fi utilizat in dispozitivelesensibile in domeniile spectrale ultraviolet si vizibil si in materialele pentru senzorii de gaze. Procedeul include amestecarea solutiilor apoase desaruri, ce contin ioni de Ga3+ si Zn2+ in raport molar de 2:1, incalzirea lenta cu agitare timp de 5 minute, dupa care se adauga solutie concentrata de amoniac, apoi amestecul este supus agitarii timp de 10…15 minute, se filtreaza, solutia ramasa sefierbe pana la pH = 7…8, precipitatul format dupafierbere se filtreaza si se calcineaza timp de 6 ore la temperatura de 700…800°Ń. Totodata, la obtinerea galatului de zinc se efectueaza doparea cu ioni de metale pamanturi rare in concentratie de 0,1…1% mol prin adaugarea la solutiile ce contin ioni de Ga3+ si Zn2+ a solutiilor apoase de saruri demetale pamanturi rare.The invention relates to the technology for obtaining the multicomponent oxide materials, in particular, to a process for obtaining the nanostructured zinc galate, which can be used in sensitive devices in the ultraviolet and visible spectral domains and in the materials for gas sensors. The process includes mixing of aqueous solutions, which contain Ga3 + and Zn2 + ions in a molar ratio of 2: 1, slow heating with stirring for 5 minutes, after which concentrated solution of ammonia is added, and then the mixture is stirred for 10 ... 15 minutes, filter, the remaining solution is boiling to pH = 7 ... 8, the precipitate formed after boiling is filtered and calcined for 6 hours at a temperature of 700 ... 800 ° Ţ. At the same time, zinc gallate is obtained by doping with rare earth metal ions in a concentration of 0.1… 1% mol by adding to the solutions containing Ga3 + and Zn2 + aqueous solutions of rare earth demethyl salts.
