Qiimaha Warshada HfB2 Hafnium Diboride budada
Sharaxaada Alaabta
Hafnium diboride (HfB2) waa crystal-madow-cawlan oo leh dhalaal macdan ah, iyo qaabdhismeedkeeda crystal waxa iska leh nidaamka laba geesoodka ah.Sifooyinkeeda kiimikaad way deggan yihiin, oo si dhib leh ayay ula falgashaa dhammaan reageyaasha kiimikaad (marka laga reebo HF) heerkulka qolka.Sida maadada dhoobada ah ee heerkulka aadka u sarreeya, hafnium diboride waxay leedahay meel dhalaalaysa oo aad u sarreeya (3380 ° C), waxaana badanaa loo isticmaalaa sida walxaha ka-hortagga ah ee jawiga kuleylka sarreeya.Waxa kale oo ay leedahay sifooyinka adag ee adag, modules sare, conductivity kaamerada sare iyo conductivity sare ee korontada, sidaas darteed waxaa si weyn loo isticmaalaa in daahan u adkaysta, qalabka refractory, qalab goynta iyo nidaamka ilaalinta kulaylka hawada hawada iyo beeraha kale.

Codsiga
1. Xiro u adkaysta dahaarka;Qalabka kiimikaad ee dahaarka iyo dahaadhka u adkaysta;walxaha isku dhafan ee ka-hortagga oksaydhka;Qalabka dib-u-celinta, dhacdooyinka ka-hortagga daxalka ee birta dhalaalaysa;
2. Waxyaabaha lagu daro kulaylka;iska caabin heerkul sare ah;heerkul sare u adkaysta, daxalka u adkaysta, iyo oxidation-u adkaysta dahaarka gaarka ah;
3. Waxaa inta badan loo isticmaalaa sida walxo soo saarista dhoobada isku dhafan;waxa loo isticmaali karaa sida nuugista neutron;
4. Ceramics heerkul sare leh, koojyada sanka ee diyaaradaha xawaaraha sare leh, duulista, hawada hawada iyo goobo kale.
Nidaamka xakamaynta tayada
Huarui waxa uu leeyahay nidaam maarayn tayo adag.Waxaan tijaabineynaa badeecada marka hore ka dib marka aan dhameyno wax soo saarkayaga, waxaanan tijaabineynaa mar kale ka hor dhalmo kasta, xitaa muunad.Oo haddii aad u baahan tahay, waxaan jeclaan lahayn inaan aqbalno qolo saddexaad inay tijaabiso.Dabcan haddii aad rabto, waxaan ku siin karnaa muunad si aad u tijaabiso.
Tayada alaabtayada waxaa dammaanad qaaday Machadka Metallurgical Sichuan iyo Guangzhou Institute of Metal Research.Wadashaqeynta muddada dheer ee iyaga lala yeesho waxay badbaadin kartaa waqti badan oo tijaabo ah macaamiisha.
