Zirconium Hmoov, Zr

Cov txheej txheem ntau lawm: Zirconium nqus cov pa hydrogen ntawm 400-800 ℃ thiab tsim cov zirconium hydride los ntawm cov txheej txheem kev hloov pauv ib ntu. Zirconium hydride yog decomposed ntawm kev kub. Feem ntau, hydrogen tuaj yeem dehydrogenated ntawm 500 ℃ hauv qab nqus ntawm 0.133 Pa, thiab hydrogen tuaj yeem tshem tawm tag nrho ntawm 800-1000 ℃.

Cov txheej txheem ntau lawm: Zirconium nqus cov pa hydrogen ntawm 400-800 ℃ thiab tsim cov zirconium hydride los ntawm cov txheej txheem kev hloov pauv ib ntu. Zirconium hydride yog decomposed ntawm kev kub. Feem ntau, hydrogen tuaj yeem dehydrogenated ntawm 500 ℃ hauv qab nqus ntawm 0.133 Pa, thiab hydrogen tuaj yeem tshem tawm tag nrho ntawm 800-1000 ℃. Zirconium hydride yog ua kom zoo dua los ntawm kev siv lub zog siab ntawm kev sib tsoo thiab lub cev qhuav dej kom ua lub ntsej muag ua cov kua roj ultrafine zirconium hmoov ua rau lub tshuab nqus tsev thiab qhov kub thiab txias.

Lub xeev ntawm kev khaws cia thiab kev thauj mus los: dej foob zirconium hmoov (zirconium hmoov feem ntau siv hauv qhov tshuaj tiv thaiv, yog qhov nplaim tawg thiab tawg, thaum lub sijhawm thauj mus los thiab kev cia siab yog dav dav hauv dej ntim) ntawm zirconium hmoov kom qhuav txoj kev: 1 nyob rau hauv argon tiv thaiv kom qhuav hauv lub tshuab nqus tsev qhov cub kom qhuav, 2 ob lub tshuab hluav taws xob twj tso kua mis tso rau huab cua mus rau hauv lub xeev nqus, qhov kub zoo tshaj plaws txog 55 degrees, thiab lwm yam.
