Dab tsi yogYttrium oxidesiv rau?
Yttrium oxideKuj tseem siv los ua kom yttrium hlau cov khoom siv hlau, uas yog cov tshuaj lim microwave zoo heev. Nws tseem yog lub sijhawm yav tom ntej-lub xeev cov khoom siv laser.Yttrium oxideyog ib qho tseem ceeb pib rau inorganic tebchaw. Rau airmetallic chemistry nws tau hloov dua siab tshiab rau ycl3 nyob rau hauv cov tshuaj tiv thaiv nrog funpochloric acid thiab ammonium chloride. YTTRium oxide tau siv nyob rau hauv kev npaj ntawm palevoskite hom qauv, yalo3, muaj chrome ions.
