High Purity Sodium Fluorosilicate | Kev Kho Dej Chaw Tsim Tshuaj

Sodium fluorosilicate tshwm li dawb siv lead ua, crystalline hmoov, los yog tsis muaj xim hexagonal crystals. Nws yog odorless thiab tasteless. Nws tus txheeb ze ceev yog 2.68; nws muaj peev xwm nqus dej noo. Nws tuaj yeem yaj hauv cov kuab tshuaj xws li ethyl ether tab sis yog insoluble hauv cawv. Solubility nyob rau hauv acid yog zoo tshaj nyob rau hauv dej. Nws tuaj yeem decomposed hauv cov tshuaj alkaline, tsim sodium fluoride thiab silica. Tom qab searing (300 ℃), nws yog decomposed rau hauv sodium fluoride thiab silicon tetrafluoride.

Toxicity

Cov khoom no yog tshuaj lom nrog cov nyhuv stimulating ntawm lub ntsws. Cov neeg ua txhaum ntawm qhov ncauj tshuaj lom yuav tau txais cov tsos mob hnyav ntawm kev puas tsuaj rau lub plab zom mov nrog cov koob tshuaj tuag yog 0.4 ~ 4g. Thaum lub sijhawm ua haujlwm ntawm tus neeg teb xov tooj, lawv yuav tsum hnav cov cuab yeej tiv thaiv tsim nyog kom tsis txhob muaj tshuaj lom. Cov khoom siv ntau lawm yuav tsum raug kaw thiab lub rooj cob qhia yuav tsum muaj qhov cua zoo.

Kev Kho Dej Sodium Silicofluoride, Sodium Fluorosilicate, SSF, Na2SiF6.

Sodium fluorosilicate tuaj yeem hu ua sodium silicofluoride, lossis sodium hexafluorosilicate, SSF. Tus nqi ntawm sodium fluorosilicate tuaj yeem ua raws li cov khoom muaj peev xwm, thiab qhov purity uas tus neeg yuav khoom xav tau.
