Scandium Carbonate

Scandium Carbonate yog dej insoluble Scandium qhov chaw uas tau yooj yim hloov mus rau lwm yam Scandium tebchaw, xws li oxide los ntawm cua sov (calcination). Carbonate tebchaw kuj muab cov pa roj carbon dioxide thaum kho nrog dilute acids. . Scandium Carbonate feem ntau muaj tam sim ntawd nyob rau hauv feem ntau ntim.

Lub scandium raw khoom ntawm Hunan oriental Scandium los ntawm cov khib nyiab acid ntawm titanium dioxide nyob rau hauv peb pab pawg neeg, LB pawg, uas yog lub ntiaj teb no 3rd loj tshaj plaws chaw tsim tshuaj paus ntawm high-zoo titanium dioxide pigments thiab 1st nyob rau hauv Asia nyob rau hauv cov nqe lus ntawm TiO2 pigment muaj peev xwm.

Hunan Oriental Scandium tau tsom mus rau kev lag luam scandium rau ntau tshaj li ib xyoo caum thiab tuaj yeem muab cov khoom siv scandium hydroxide rau kev npaj ntawm scandium oxalate, scandium oxide thiab ntau lub tebchaw uas muaj scandium.

Daim ntawv thov

Scandium Carbonate tuaj yeem siv rau hauv kev npaj ntawm lwm cov tshuaj scandium nrog rau hauv cov tshuab kub kub vim nws tsis kam ua kom sov thiab thermal shock. Nws yog cov khoom siv pab hauv iav muaj pes tsawg leeg. Tsis tas li ntawd, Scandium Carbonate yog ib hom reagent.

Scandium yog qhov zoo tshaj plaws refiner thiab hloov kho rau aluminium alloys, nws tuaj yeem txhim kho lub zog, plasticity, vuam, corrosion, ua thiab xim cov khoom ntawm aluminium alloy.Scandium thaum alloyed nrog txhuas tsim ib qho ntawm cov muaj zog tshaj plaws - thiab lightest - alloys.

FAQs

Scandium yog dab tsi?

Scandiumyog cov khoom siv tshuaj uas sawv cev los ntawm lub cim Sc ntawm lub rooj zaum. Lub ntsiab lus Sc muaj tus lej atomic ntawm 21, uas yog hais txog tus naj npawb ntawm cov protons hauv ib qho atom ntawm lub caij no. Lub ntsiab lus no nrog 21 protons yog thawj zaug kwv yees muaj nyob rau hauv 1871 los ntawm Lavxias teb sab chemist Dmitry Mendeleyev, uas hu ua nws ekaboron. Mendeleyev yog lub npe hu ua 'Leej Txiv ntawm Lub Sij Hawm Lub Sij Hawm ntawm Cov Ntsiab Lus'.

Thawj qhov sib xyaw scandium, scandium oxide, tau pom ua ntej cov khoom raug cais tawm hauv nws daim ntawv ntshiab. Nws tau tshawb pom los ntawm Swedish chemist hu ua Lars Fredrik Nilson hauv xyoo 1879, thiab cov oxide no tau raug hu ua scandia tom qab tus kws tshuaj hauv tebchaws - Scandinavia. Lub caij, nyob rau hauv lem, tau hu ua scandium tom qab lub cheeb tsam nws tau pom nyob rau hauv.
