V\u011bd\u011bli jste, \u017ee hlin\u00edk je jedn\u00edm z nejpou\u017e\u00edvan\u011bj\u0161\u00edch prvk\u016f na Zemi?<\/h3>\n

Je velmi v\u0161estrann\u00fd a lze jej vyu\u017e\u00edt na mnoha r\u016fzn\u00fdch \u00farovn\u00edch k r\u016fzn\u00fdm \u00fa\u010del\u016fm. Pou\u017e\u00edv\u00e1 se ji\u017e velmi dlouho, pot\u00e9, co ji v roce 1825 poprv\u00e9 objevil Hans Christian Oersted. Hlin\u00edk pou\u017e\u00edv\u00e1me v ka\u017edodenn\u00edm \u017eivot\u011b a v \u0159ad\u011b r\u016fzn\u00fdch situac\u00ed.<\/p>\n

Chemick\u00e9 vlastnosti<\/h3>\n

Existuj\u00ed jak fyzick\u00e9, tak chemick\u00e9 vlastnosti<\/a> kter\u00e9 je d\u016fle\u017eit\u00e9 pochopit. Ob\u011b tyto vlastnosti se kombinuj\u00ed dohromady, aby vytvo\u0159ily celkov\u00fd produkt a to, co nakonec z\u00edsk\u00e1te. Pod\u00edv\u00e1me se na fyzik\u00e1ln\u00ed i chemick\u00e9 vlastnosti.<\/p>\n

Mezi fyzik\u00e1ln\u00ed vlastnosti pat\u0159\u00ed: v\u00fdrazn\u00e1 barva, kter\u00e1 jej odli\u0161uje od ostatn\u00edch kov\u016f. Zd\u00e1 se, \u017ee m\u00e1 b\u00edlou\/st\u0159\u00edbrnou barvu. Teplota 660,4 \u00b0C je bod t\u00e1n\u00ed hlin\u00edku. Va\u0159\u00ed se p\u0159i teplot\u011b 4472,33 Fahrenheita. Hmotnost hlin\u00edku je 26,98154, atomov\u00fd polom\u011br 143,1 pm. Je to nemagnetick\u00fd materi\u00e1l a tak\u00e9 kujn\u00fd. V hlin\u00edku se vyskytuj\u00ed t\u0159i izotopy a uvnit\u0159 16 um\u011bl\u00fdch izotop\u016f.<\/p>\n

Mezi chemick\u00e9 vlastnosti pat\u0159\u00ed: AL tvo\u0159\u00ed p\u0159i styku s kysl\u00edkem tzv. oxid hlinit\u00fd. Ten je zn\u00e1m jako slupka, proto\u017ee poskytuje materi\u00e1lu ochrannou vrstvu, kter\u00e1 jej chr\u00e1n\u00ed p\u0159ed koroz\u00ed. P\u0159esto\u017ee tato slupka slou\u017e\u00ed k ochran\u011b, hlin\u00edk je vysoce ho\u0159lav\u00fd materi\u00e1l, kter\u00fd se m\u016f\u017ee snadno vzn\u00edtit, pokud je vystaven plamen\u016fm a je st\u00e1le v pr\u00e1\u0161kov\u00e9 form\u011b. L\u00e1tky a kyseliny reaguj\u00ed na slou\u010deninu hlin\u00edku.<\/p>\n

D\u00edky kombinaci fyzik\u00e1ln\u00edch a chemick\u00fdch vlastnost\u00ed hlin\u00edku se z n\u011bj snadno st\u00e1v\u00e1 univerz\u00e1ln\u00ed kov. Hlin\u00edk lze ve form\u011b kovu pou\u017e\u00edt k v\u00fdrob\u011b nejr\u016fzn\u011bj\u0161\u00edch v\u00fdrobk\u016f. Je pravd\u011bpodobn\u00e9, \u017ee i vy pou\u017e\u00edv\u00e1te n\u011bkolik v\u00fdrobk\u016f, kter\u00e9 byly vyrobeny z hlin\u00edku. Ventily tlakov\u00fdch my\u010dek, \u010derpadla a p\u0159evodovky se skl\u00e1daj\u00ed p\u0159ev\u00e1\u017en\u011b z tlakov\u011b lit\u00e9 slitiny AL. AL materi\u00e1l je nejpou\u017e\u00edvan\u011bj\u0161\u00edm materi\u00e1lem v automobilech.<\/a>.<\/p>\n

Hlin\u00edk se tak\u00e9 \u010dasto pou\u017e\u00edv\u00e1 k v\u00fdrob\u011b pr\u016fmyslov\u00fdch stroj\u016f a za\u0159\u00edzen\u00ed. tlakov\u011b lit\u00e9 d\u00edly<\/a>.<\/p>\n
