Tungsten Trioxide Description
Tungsten trioxide, tseem hu ua tungsten (VI) oxide, tungstic anhydride los yog daj tungsten, yog ib qho thermally ruaj khov thiab dej-insoluble tungsten compound. Nws yog soluble hauv alkali thiab me ntsis soluble hauv acid. Nws yog siv los tsim high melting point alloy, tungsten filament thiab hluav taws pov thawj cov ntaub ntawv. Nws tuaj yeem ua los ntawm melting tungsten ore thiab alkali nrog acid.
Tungsten trioxide feem ntau muaj tam sim ntawd nyob rau hauv feem ntau ntim. Ultra siab purity, siab purity, submicron thiab nanopowder cov ntaub ntawv yuav raug txiav txim siab. Peb kuj muab tungsten oxide hmoov nrog lwm yam xim xws li xiav thiab ntshav.
