Daim ntawv thov:
Yttrium Nitrate yog siv rau hauv ceramics, iav, thiab electronics. Cov qib purity siab yog cov ntaub ntawv tseem ceeb tshaj plaws rau tri-bands Rare Earth phosphors thiab Yttrium-Iron-Garnets, uas yog cov lim dej microwave zoo heev. Yttrium Nitrate yog cov dej soluble crystalline heev Yttrium qhov chaw siv tau tshaj nitrates thiab qis dua (acidic) pH.Siv hauv kev lag luam xws li kev tsim khoom ternary catalysts, yttrium tungsten electrodes, ceramic khoom, intermediates ntawm yttrium tebchaw, tshuaj reagents.Reagents, As ib qhov chaw ntawm yttrium, nws yog siv los tsim mesophase surfactants Raws li yttrium, raws li ib tug adsorbent los yog ua ib tug precursor rau kho qhov muag functional tshuaj thiab nano scale coatings ntawm carbon composite cov ntaub ntawv.

Nco tseg: Kev tsim khoom thiab ntim khoom tuaj yeem ua raws li cov neeg siv khoom tshwj xeeb.
Cov txheej txheem ntau lawmntawm yttrium nitrate: nyob rau hauv cua sov, me ntsis tshaj yttrium oxide yog yaj nyob rau hauv concentrated nitric acid kom tau nws. Hlawv yttrium oxide ntawm 900 ℃ rau 3 teev, txias thiab yaj hauv 1: 1 nitric acid tov. Tswj pH ntawm cov tshuaj thaum kawg ntawm cov tshuaj tiv thaiv kom 3-4. Distilled cov tshuaj nyob rau hauv lub siab txo mus rau hauv ib tug syrup thiab maj mam crystallize nyob rau hauv chav tsev kub. Recrystallize ob zaug. Thaum recrystallizing, ib qho me me ntawm yttrium nitrate yuav tsum tau ntxiv los ua cov noob kom tau yttrium nitrate hexahydrate siv lead ua.
