1. Ihe omimi nkesayensimmewere

Na-agbazesayensiBụ 1541 ℃, isi mmiri bụ 2836 ℃, na njupụta bụ 2.985 g / cm³. Scandium bụ ọkụ, ọla ọcha-ọcha nke na-emegharị kemịlị ma nwee ike imeghachi na mmiri ọkụ iji mepụta hydrogen. Ya mere, ihe nlere nke igwe ị na-ahụ na eserese ahụ na karama ma chebe ikuku argon. Ma ọ bụghị ya, Scandium ga-etolite ngwa ngwa na-acha odo odo ma ọ bụ ntụ ntụ oyi akwa ma tufuo ihe na-egbu mara mma.    

2. Isi nke Scandium

Ojiji nke Scandium (dị ka isi ihe na-arụ ọrụ, ọ bụghị maka doping) na-etinye uche na ntuzi aka dị mma, ọ bụghịkwa ikwubiga okwu ókè iji kpọọ ya nwa nke ìhè.

Nke a bụ usoro ọkụ ọkụ na-eme ka ọkụ eletrik: bọlbụ jupụtara sodium iodide na scandium, a na-agbakwunye Scandium na sodium foil n'otu oge. N'oge mwepu nke elu voltaji, eyịm scandium na sodium emit na-egosipụta n'ụzọ ha nwere ike ijegharị. Mpempe akwụkwọ dị iche iche sodium bụ ụzarịba abụọ a ma ama na 589.0 na 589.6M, ebe oghere dị na mbara igwe na-acha anụnụ anụnụ na 361.3 ruo 424.7.7N. N'ihi na ha na-agbazi agba agba, agba dị n'ozuzu ya na-amịpụta bụ ìhè ọcha. Ọ bụ n'ụzọ ziri ezi n'ihi na oriọna Spidium nwere njiri mara oke nke arụmọrụ dị elu, ndụ dị mma, ndụ na-eme ka a na-eme ihe na mbara igwe, na-akpọkwa ọgbọ nke atọ. Light Isi mmalite. Na China, ụdị oriọna a na-akwalite dị ka teknụzụ ọhụrụ, mana na mba ụfọdụ mepere emepe, a na-eji ụdị oriọna a ebe mmalite afọ 1980s.

2). Mkpụrụ ndụ solovovtatic celks nwere ike ịnakọta ọkụ ahụ gbasasịrị n'elu ma mee ka ọ bụrụ eletrik na-egbochi ọha mmadụ. Scandium bụ igwe ihe mgbochi kachasị mma na Metal-insulator-semiconductor silicon Photovtatic sel na sel anyanwụ

3). Gamma Ray, ngwa agha a nwere ike ibute oke ọkụ site n'onwe ya, mana ụdị ọkụ anyị enweghị ike ịnabata ụdị ọkụ a. Ọ bụ Photon Photon na-abanye. Ihe anyị na-ewepụta site na mineral bụ 45sc, nke bụ naanị ọdịdị eke nke scandium. Nke ọ bụla 45sc nucleus nwere ihe ọmụmụ iri abụọ na ise na nnọpụ 24. Ọ bụrụ na anyị etinye Scandium na ihe nuklia na-emegharị neutron neutron na-eme ka ọ dị neutron Neutron, dị ka itinye enwe na taingy ụbọchị 7,749, 46SC na otu neutrọs ọzọ ọzọ na nuckleus ọzọ. 46SC, enwere ike iji Itope redio, mee ihe dị ka ihe isi iyi ma ọ bụ tracer atọ, enwere ike iji ya mee ihe maka ọgwụ ọjọọ. Enwere ọtụtụ ndị na-ejikwa YTtrium-Scandium-Scandium nke Garners, iko fluride fluride na-enweghị atụ, na camndium cat tubes na televishọn. Ọ dị ka a ga - eme ka scandium na - enwu gbaa.

3, ogige nke scdium    1). Terbium scandate (TBSCO3) kristal - nwere ezigbo lattice na-eme ka ọ bụrụ survskite supercontic na-enweghị atụ

2).Aluminom scandium alloy- Nke mbu, ọ bu aluminom di elu. E nwere ọtụtụ ụzọ iji meziwanye arụmọrụ nke alloys aluminom. N'ime ha, microlowy na na-ewusi ike na ume ha abụwo ụzọ nke usoro allay dị elu n'ime afọ 20 gara aga. Na mbugharị, aerospace atụmanya ngwa dị na mpaghara ndị dị elu dịka ụlọ ọrụ, akụ ụtarị roket, na ike nuklia sara mbara.

3).Scandium oxide- Scandium oxide nwere ezigbo anụ ahụ na kemịkal akụrụngwa dị iche iche, yabụ, nwere ọtụtụ ngwa dị na Science sayensị. E nwere ike iji Scandium sidide dị ka ihe mgbakwunye na akụrụngwa caramiiki, nke nwere ike ime ka ihe siri ike, ike na-eyi ike iguzogide seramic, na-eme ka ha nọrọgidekwuo ike. Na mgbakwunye, enwere ike iji Scandium side iji kwadebe ihe owuwu oke ikuku. Ihe ndị a na-egosipụta ezi echiche eletriki na obere okpomọkụ ma nwee nnukwu ngwa.
