Basic Knowledge Ntawm Titanium

Titanium yog cov khoom siv hlau nrog cov cim tshuaj Ti thiab atomic naj npawb 22, koom nrog pawg IVB ntawm cov ntsiab lus hlau ntawm lub rooj zaum. Titanium lub melting point 1660 degree, boiling point 3287 degree, ceev 4.54g/cm³. Titanium yog grey hloov hlau uas muaj lub teeb yuag, siab zog thiab zoo corrosion kuj. Vim nws cov khoom siv tshuaj ruaj khov, ua haujlwm zoo rau qhov kub thiab txias, muaj zog acids thiab alkalis, nrog rau lub zog siab thiab qhov ntom ntom, nws yog hu ua "qhov chaw hlau". Qhov sib xyaw ua ke ntawm titanium feem ntau yog titanium dioxide (feem ntau hu ua titanium dioxide), thaum lwm cov tshuaj muaj xws li titanium tetrachloride thiab titanium trichloride. Titanium yog ib qho ntawm cov khoom siv dav tshaj plaws hauv ntiaj teb, suav nrog 0.16% ntawm qhov loj ntawm lub ntiaj teb crust, qeb thib cuaj. Lub ntsiab ore ntawm titanium yog ilmenite thiab rutile. Ob qhov zoo tshaj plaws ntawm titanium yog lub zog tshwj xeeb thiab kev tiv thaiv corrosion, uas txiav txim siab tias titanium yog khi kom muaj kev cog lus rau hauv aerospace, riam phom, lub zog, tshuaj lom neeg kev lag luam, metallurgy, kev tsim kho thiab kev thauj mus los. Muaj ntau reserves ntawm titanium muab lub hauv paus rau kev siv dav ntawm titanium.
