Ngwaahịa Carbide Cemented Tungsten Nkwadebe ntụ ntụ

Ultra-mma urughuru tungsten ntụ ntụ bụ nwa, ezigbo urughurutungstenntụ ntụ bụ ọchịchịrị isi awọ, na keadighi rarii urughuru tungsten ntụ ntụ bụ ìhè isi awọ na dara luster.Enwere ike ịmepụta ntụ ntụ tungsten metal site na ibelata tungsten oxide.Ụzọ mbelata isi bụ mbelata hydrogen na mbelata carbon.Ka ọ dị ugbu a, a na-ejikarị usoro mbelata hydrogen.Mmekọrịta nke hydrogen na oxygen na okpomọkụ dị elu dị ukwuu karịa njikọ nke tungsten na oxygen.Ya mere, tungsten trioxide na-amalite ibelata site na hydrogen na 380 ~ 400 ° C.Hydrogen nwere ike ibelata tungsten dioxide n'imetungsten ntụ ntụn'elu 630 ° C.

.Thetungsten ntụ ntụemepụtara site na usoro mbelata hydrogen nwere ịdị ọcha dị elu ma dị mfe ijikwa nha nha nke ntụ ntụ.Na enweghị hydrogen, usoro mbelata carbon dịkwa.Uru nke ahịhịa akọrọ bụ na carbon ojii dị ọnụ ala ma dị mfe ịnweta, mana nha nke ntụ ntụ siri ike ịchịkwa.Enwere usoro mbelata nke otu oge maka ibelata tungsten oxide na hydrogen iji dozie ntụ ntụ tungsten, enwerekwa usoro mbelata nke ọtụtụ ọkwa nke mbụ na-ebelata WO3 ka WO2, wee belata oxalic acid buru ụzọ mepụta w ntụ ntụ.Na usoro mmepụta nke ugbu a, tungsten ntụ ntụ na-emekarị site na otu usoro mbelata kpọmkwem.

Na mgbakwunye, enwerekwa usoro iji belata ammonium paratungstate ozugbo n'ime ntụ ntụ tungsten.A na-akwadokwa tungsten ụfọdụ ebumnuche pụrụ iche site na usoro mbelata halide.
Enwekwara usoro aluminothermic iji belata ntụ ntụ ma kwadebe ya.Kemgbe 2000, a na-akwalite usoro nke ịkwadebe ntụ ntụ ultrafine tungsten site na mbelata hydrogen nke violet tungsten.
