Tus neeg sawv cev txo qis siv hauv cov txheej txheem thermite yog Aluminium.

Nws yog siv los ua qhov txo qis hauv cov txheej txheem thermite?

Sodium. Lus Qhia: Peb paub tias cov txheej txheem thermite yog txheej txheem uas cov hlau oxides raug txo los ntawm kev siv txhuas hmoov. Yog tias qhov sib xyaw ntawm aluminium thiab oxide yog rhuab, aluminium tau oxidized thaum hlau oxide tau txo.

Vim li cas txhuas siv los ua tus neeg sawv cev txo qis hauv Goldsmith thermite txheej txheem?

Ua tiav cov kauj ruam los ntawm kev daws teeb meem: Alumino thermite yog txheej txheem ntawm kev rho tawm cov hlau los ntawm kev txo cov hlau oxide los ua cov hlau siv cov hmoov txhuas, cov txhuas ua los ntawm kev txo tus neeg sawv cev. Nws yog ib qho exothermic cov tshuaj tiv thaiv uas tso cov cua sov ntau.

Cov txheej txheem Goldsmith thermite yog dab tsi?

Cov Txheej Txheem Thermite lossis Goldschmidt Txheej Txheem yogtxoj hauv kev kom tau cov hlau ua kua los ntawm kev txo cov oxide nrog txhuas hmoov, thaum ignited nrog magnesium ribbon nws reacts los ntawm kev tsim hlau thiab txhuas oxide. ntawm qhov kub siab heev nce mus txog 3000 degrees Celsius.

Cov hlau twg yog siv hauv cov txheej txheem kub kub?

teb cov lus teb ib kauj ruam dhau los: Cov txheej txheem Goldschmidt thermite yog txheej txheem ntawm kev rho tawm cov hlau los ntawm kev txo cov hlau oxide los ua cov hlau siv txhuas hmoov, cov txhuas ua raws li tus kws txo qis.
