Isi ụzọ maka imepụta ntụ ntụ Tungsten

Tungsten ntụ ntụ bụ isi akụrụngwa maka mmepụta nke tungsten carbide, tungsten dị ọcha, tungsten alloys na ngwaahịa tungsten ndị ọzọ, ihe karịrị 70% nke tungsten ntụ ntụ na-eji na mmepụta nke tungsten carbide. Ugbu a, ụzọ ndị bụ isi maka inweta ntụ ntụ tungsten bụ:

Usoro mbelata hydrogen nke tungsten oxide

Nke a bụ usoro iji belata tungsten oxide na ntụ ntụ tungsten na-eji H2 dị ka onye na-ebelata ihe. N'iji mbelata hydrogen nke WO₃ dịka ọmụmaatụ, mmeghachi omume n'ozuzu ya bụ:

WO₃+3H₂=W+3H₂O

Ugbu a, tungsten oxides eji dị ka akụrụngwa maka hydrogen mbelata tumadi gụnyere odo tungsten trioxide (WO₃), blue tungsten oxide (tumadi WO₂.₉), na purple tungsten oxide (WO₂.₇₂), wdg The hydrogen mbenata usoro nke tungsten oxide bụ isi usoro maka imepụta tungsten metal powder ugbu a.

2. Mbelata hydrogen nke tungsten halides

Nke a bụ usoro nke na-eji H2 dị ka onye na-ebelata ego iji belata tungsten halides (dị ka tungsten chloride, tungsten fluoride) na tungsten dara. Dịka ọmụmaatụ, n'ihe gbasara mbelata hydrogen nke WCl6, mmeghachi omume n'ozuzu ya bụ:

WCl6+3H₂=W+6HCI

Usoro mbelata hydrogen nke tungsten halides bụ mmeghachi omume gas-phase, nke a na-ejikarị na ikuku kemịkalụ iji mepụta ntụ ntụ ultrafine tungsten ma ọ bụ mkpuchi tungsten. Ugbu a, a na-eji usoro mbelata chlorination nke tungsten halides naanị maka mmepụta obere ihe.

3. Ụzọ Mbelata Carbon nke Tungsten Oxides

Mgbe ngwakọta nke tungsten oxides na carbon na-ekpo ọkụ na okpomọkụ ụfọdụ, tungsten oxides na-ebelata ka ọ bụrụ tungsten ntụ ntụ. N'iji mbelata carbon nke WO₃ dịka ọmụmaatụ, mmeghachi omume n'ozuzu ya bụ:

WO₃+3C=W+3CO

WO₃+3CO=W+3CO₂

Mgbe ụfọdụ, a na-ewebata obere hydrogen n'ime ọkụ iji kwalite usoro mbelata carbon. Otú ọ dị, ntụ ntụ tungsten nke usoro a na-emepụta nwere ihe dị elu nke carbon na ọ dịghị adabara ngwaahịa tungsten. Ka ọ dị ugbu a, usoro mbelata carbon maka ịkwadebe ntụ ntụ tungsten na-adị obere, mana a na-etinyekwu ya na mmepụta nke tungsten carbide kpọmkwem, karịsịa ultrafine tungsten carbide powder na tungsten carbide composite powder.

4. Ụzọ ndị ọzọ

Ụzọ ndị ọzọ maka imepụta tungsten ọla gụnyere electrolysis nnu gbazere, mbelata zinc, na mbelata hydrogen plasma, n'etiti ndị ọzọ.
