Isima ya Carbide Ibicuruzwa bya Tungsten Gutegura ifu

Ultra-nziza ya tungsten ifu ni umukara, agace kezatungstenifu ni umukara wijimye, naho ifu ya tungsten ifu yoroheje yijimye hamwe nicyuma.Ifu ya tungsten y'ibyuma irashobora kubyara mukugabanya okiside ya tungsten.Uburyo nyamukuru bwo kugabanya ni kugabanya hydrogen no kugabanya karubone.Kugeza ubu, uburyo bwo kugabanya hydrogen bukoreshwa.Ubusabane bwa hydrogène na ogisijeni ku bushyuhe bwinshi burenze ubwinshi bwa tungsten na ogisijeni.Kubwibyo, tungsten trioxide itangira kugabanuka na hydrogen kuri 380 ~ 400 ° C.Hydrogen irashobora kugabanya dioxyde ya tungstenifu ya tungstenhejuru ya 630 ° C.

.Theifu ya tungstenbyakozwe nuburyo bwo kugabanya hydrogène bifite isuku nyinshi kandi biroroshye kugenzura ingano yifu yifu.Mugihe habuze hydrogène, uburyo bwo kugabanya karubone nabwo burahari.Ibyiza byibyatsi byumye nuko umukara wa karubone uhendutse kandi byoroshye kuboneka, ariko ingano yifu yifu iragoye kuyigenzura.Hariho uburyo bumwe bwo kugabanya inshuro imwe yo kugabanya okiside ya tungsten hamwe na hydrogène kugirango utegure ifu ya tungsten, kandi hariho nuburyo bwo kugabanya ibyiciro byinshi bibanza kugabanya WO3 kugeza kuri WO2, hanyuma bikagabanya aside ya oxyde mbere yo gukora ifu ya w.Mubikorwa byubu, umusaruro wa tungsten mubusanzwe ukorwa muburyo bumwe bwo kugabanya.

Mubyongeyeho, hariho nuburyo bwo kugabanya mu buryo butaziguye ammonium paratungstate mu ifu ya tungsten.Bimwe bidasanzwe-bigamije tungsten nayo yateguwe nuburyo bwo kugabanya igice.
Hariho kandi uburyo bwa aluminothermic bwo kugabanya ifu yamabuye no kuyitegura.Kuva mu 2000, gahunda yo gutegura ifu ya ultrafine tungsten ikoresheje hydrogène yo kugabanya violet tungsten yatejwe imbere cyane.
