Tantalum pentoxide (Ta2O5) yog xim dawb crystalline hmoov, feem ntau oxide ntawm tantalum, thiab cov khoom kawg ntawm tantalum hlawv hauv huab cua. Nws yog tsuas yog siv rau rub lithium tantalate ib leeg siv lead ua thiab tsim tshwj xeeb iav iav nrog siab refraction thiab tsawg dispersion. Nws tuaj yeem siv los ua catalyst hauv kev lag luam chemical.
Kev siv thiab kev npaj
【siv】
Cov khoom siv raw rau kev tsim cov hlau tantalum. Kuj tseem siv tau hauv kev lag luam hluav taws xob. Nws yog siv los rub lithium tantalate ib leeg siv lead ua thiab tsim tshwj xeeb iav iav nrog siab refraction thiab tsawg dispersion. Nws tuaj yeem siv los ua catalyst hauv kev lag luam chemical.
【Kev npaj lossis qhov chaw】
Potassium fluorotantalate txoj kev: Cua sov poov tshuaj fluorotantalate thiab sulfuric acid rau 400 ° C, ntxiv dej rau cov reactants kom txog thaum boiling, tag nrho diluting acidified tov rau hydrolyze, tsim hydrated oxide precipitates, thiab ces sib cais, ntxuav, thiab ziab kom tau pentoxide Ob tantalum khoom. .
2. Hlau tantalum oxidation txoj kev: dissolve hlau tantalum flakes nyob rau hauv nitric acid thiab hydrofluoric acid tov acid, extract thiab purify, precipitate tantalum hydroxide nrog ammonia dej, ntxuav nrog dej, qhuav, hlawv thiab grind finely kom tau tantalum pentoxide tiav cov khoom.
Kev nyab xeeb ntim rau hauv polyethylene yas fwj nrog ob txheej hau, txhua lub raj mis muaj qhov hnyav ntawm 5kg. Tom qab raug kaw kom nruj, lub hnab yas polyethylene sab nraud tau muab tso rau hauv ib lub thawv tawv, ntim nrog cov ntawv pov tseg kom tsis txhob txav mus los, thiab txhua lub thawv muaj qhov hnyav ntawm 20kg. Khaws nyob rau hauv qhov chaw uas muaj cua, qhuav, tsis stacked nyob rau hauv qhib cua. Ntim yuav tsum raug kaw. Tiv thaiv los ntawm nag thiab ntim khoom puas tsuaj thaum thauj. Thaum hluav taws kub, dej, xuab zeb thiab hluav taws tua hluav taws tuaj yeem siv los tua hluav taws. Toxicity thiab Kev Tiv Thaiv: Cov plua plav tuaj yeem ua rau lub qhov txhab ntawm cov kab mob ua pa, thiab cov plua plav mus ntev tuaj yeem ua rau mob pneumoconiosis. Qhov siab tshaj plaws tso cai ntawm tantalum oxide yog 10mg / m3. Thaum ua haujlwm nyob rau hauv ib puag ncig nrog cov hmoov av siab, nws yog ib qho tsim nyog yuav tsum tau hnav lub npog ntsej muag roj, tiv thaiv cov pa tawm ntawm oxide plua plav, thiab siv tshuab thiab kaw cov txheej txheem crushing thiab ntim.
