Hlau yog inorganic thiab feem ntau muaj crystalline lug thiab yog khoom. Txhua yam koj xav tau yog rau qhov ntawd hlau tshwm sim lawm ntawm nws haiv neeg daim ntawv rau nws ua ib tug ntxhia . Txawm li cas los xij, muaj cov xwm txheej uas muaj hlau, ib txwm muaj hlau tau pom, feem ntau nyob rau hauv meteorites, yog li Hlau yog ib qho hlau. ntxhia.

Ib yam li ntawd ib tug yuav nug, dab tsi hlau kuj yog minerals?

Cov hlau yog cov khoom tseem ceeb, xws li kub , nyiaj thiab tooj liab uas yog crystalline thaum khoom thiab ib txwm tshwm sim hauv cov zaub mov. Lawv feem ntau muaj cov yam ntxwv ntawm kev ua tau zoo ntawm hluav taws xob thiab hluav taws xob, ntawm kev ci ntsa iab hauv qhov tsos thiab ua tau yooj yim.

Ib yam li ntawd, tooj liab puas yog hlau lossis ntxhia? Tooj Qhov tseeb: Tooj Cov Hlau . Tooj yog a ntxhia thiab ib qho tseem ceeb rau peb lub neej txhua hnub. Nws yog ib qho kev lag luam loj hlau vim nws siab ductility, malleability, thermal thiab hluav taws xob conductivity thiab tsis kam mus corrosion. Nws yog ib qho tseem ceeb hauv peb cov khoom noj txhua hnub.

Kuj paub, cov zaub mov thiab cov hlau yog tib yam?

Hlau yog cov element hos cov ntxhia yog cov sib txuas ntawm ntau yam. Hlau tsis tshua muaj tshwm sim nyob rau hauv haiv neeg daim ntawv tsuas yog ob peb hlau xws li kub, nyiaj, tooj liab thiab lwm yam. Cov ntxhia yog ib yam khoom inorganic uas muaj cov tshuaj muaj pes tsawg leeg, atomic qauv thiab tshwm sim nyob rau hauv xwm. Piv txwv li hlau (Fe) yog a hlau.

Yog ntsev yog ib qho ntxhia?

Ntsev yog a ntxhia muaj feem ntau ntawm sodium chloride (NaCl), cov tshuaj sib xyaw ua ke ntawm cov ntsev loj dua; ntsev nyob rau hauv nws daim ntawv ntuj raws li ib tug crystalline ntxhia yog lub npe hu ua pob zeb ntsev los yog halite. Ntsev yog tam sim no nyob rau hauv ntau ntau nyob rau hauv seawater, qhov twg nws yog lub ntsiab ntxhia lub hauv paus.
