Ukuhola

Umthofu unokubukeka okumhlophe okwesibhakabhaka nokucwebezela okugqamile. Inenombolo ye-athomu engu-82, isisindo se-athomu ingu-207.2, indawo yokuncibilika engu-327.46 ℃ kanye nephuzu elibilayo elingu-1740℃. Ayincibiliki emanzini, futhi iyathandeka futhi i-ductile, kanye ne-conductor empofu kagesi. Ithathwa njengento esinda kakhulu, engeyona imisebe enesakhiwo sekristalu eyi-cubic egxile ebusweni.

Umthofu umelana kakhulu nokugqwala. Inezinzuzo zendawo encibilikayo ephansi kanye ne-ductility enhle kakhulu futhi ingakhiwa ibe amapuleti, amashubhu, futhi ingasetshenziswa ezinhlelweni eziningi nasezimbonini, njengobunjiniyela bamakhemikhali, izintambo zikagesi, ibhethri lesitoreji kanye nokuvikelwa kwe-radiological. Umthofu ungaba impahla eluhlaza yezinhlamvu, izintambo zikagesi, isivikelo semisebe, noma njenge-alloying element yokuthuthukisa izici ezithile zomshini ezifana nobude, ubulukhuni, namandla aqinile.

Umthofu uthathwa njengenye yezinsimbi ezinzile kakhulu, awuncibiliki ku-hydrochloric noma i-sulfuric acid, kungaba yinto efanelekile yokuthwala insimbi nama-solder. Ngaphandle kwalokho, Umthofu ungaba isizinzisi se-asphalt egandaywe esetshenziswa ekwakhiweni komgwaqo.

I-Rich Special Materials Ingumkhiqizi Wethagethi Ye-Sputtering futhi ingakhiqiza Izinto Zokungcolisa Umthofu ngokuya ngokucaciswa kweKhasimende. Ukuze uthole ukwaziswa okwengeziwe, sicela usithinte.
