Metallic sodium muaj cov tshuaj lom neeg hauv qab no:
1. Cov txheej txheem sab nraud ntawm sodium atom tsuas muaj ib qho hluav taws xob, uas yooj yim rau poob, yog li nws muaj zog txo cov khoom.
2. Sodium tuaj yeem cuam tshuam ncaj qha nrog cov khoom tsis yog xim hlau nrog cov electronegativity loj, xws li oxygen, sulfur, nitrogen, hydrogen thiab halogens, thiab feem ntau tsim cov ionic compounds.
3. Thaum qhov kub thiab txias, sodium tuaj yeem tshem tawm cov pa oxygen los ntawm oxides lossis chlorine los ntawm cov tshuaj chlorides kom txo tau cov hlau.
4. Sodium thiab nws cov ions muaj cov yam ntxwv ntawm cov nplaim xim - daj, yog li cov nplaim xim cov tshuaj tiv thaiv feem ntau yog siv los kuaj lawv hauv analytical chemistry.
Daim ntawv thov ntawm hlau sodium yog dav heev, suav nrog tab sis tsis txwv rau cov hauv qab no:
1. Raws li tus neeg sawv cev txo qis, nws yog siv hauv kev lag luam tiv thaiv kom txo cov hlau xws li titanium, zirconium, niobium, thiab tantalum los ntawm lawv cov molten halides.
2. Nyob rau hauv cov khoom siv tshuaj raw khoom, nws yog siv los tsim ntau yam tshuaj uas muaj sodium, xws li sodium butyl roj hmab, sodium hydride, sodium peroxide, sodium cyanide, thiab sodium carbonate.
3. Los tsim cov alloys, xws li sodium amalgam raws li tus neeg saib xyuas kev txo qis hauv cov organic synthesis, sodium-lead alloys rau kev tsim cov roj av los tiv thaiv kev sib tsoo, thiab sodium-potassium alloys ua coolants thiab kub exchangers rau nuclear reactors.
4. Raws li lub teeb hluav taws xob, lub teeb hluav taws xob muaj zog sodium yog dav siv nyob rau hauv txoj kev loj teeb pom kev zoo vim lawv lub teeb daj pos huab-xws li lub zog.
5. Nyob rau hauv kev lag luam khoom noj khoom haus, raws li ib tug neutralizing tus neeg sawv cev thiab leavening neeg sawv cev, nws yog siv nyob rau hauv zus tau tej cov amino acids, soy sauce thiab hmoov-raws li zaub mov.
6. Hauv kev lag luam metallurgical, nws yog siv los ua smelting flux, flotation agent rau ore hnav khaub ncaws, thiab desulfurizer hauv steelmaking thiab antimony smelting.
