Hafnium foda
Bayanin Samfura
Hafnium foda karfe ne na fari-zurfa, dangane da kayan jiki, garin hafnium yana da ma'ana mai yawa da ma'aunin tafasasshen zafi, inda yake narkewa 2545 ° C, tafasar 3876 ° C. Hakanan yana da haɓakar thermal conductivity. da high resistivity, don haka ana amfani da shi sau da yawa wajen kera superalloys da kayan lantarki.Dangane da kaddarorin sinadarai, hafnium foda yana da sauƙin amsawa tare da abubuwan da ba ƙarfe ba kamar oxygen da nitrogen don samar da daidaitattun oxides da nitrides.Hakanan yana samar da gami da karafa da yawa, kamar gami da tushen hafnium.Dangane da amfani da mahimmanci, hafnium foda abu ne mai mahimmanci, wanda aka yi amfani dashi sosai a sararin samaniya, soja, lantarki da sauran fannoni.Alal misali, an haɗa shi da tungsten, rhenium da sauran karafa zuwa gaɗaɗɗen ƙarfi mai ƙarfi, masu tsayayyar zafin jiki na tushen hafnium don kera injunan jirage da injunan roka.Bugu da ƙari, ana iya amfani da foda na hafnium don kera kayan aikin lantarki, kamar capacitors, resistors, da dai sauransu.

Hafnium Hf foda galibi ana amfani dashi don:
1. Yawanci amfani da X-ray cathode da tungsten waya masana'antu;
2. Hafnium mai tsabta yana da fa'idodin filastik, sauƙin sarrafawa da juriya na lalata yanayin zafi, kuma abu ne mai mahimmanci a cikin masana'antar makamashin atomic;
3. Hafnium yana da babban sashin kama neutron na thermal, yana mai da shi kyakkyawan abin sha na neutron, wanda za'a iya amfani dashi azaman sandar sarrafawa da na'urar kariya a cikin injin atomatik;
4. Hafnium foda za a iya amfani da shi azaman propellant don roka
5. Hafnium za a iya amfani da a matsayin getter da yawa inflatable tsarin.Hafnium getter na iya cire iskar oxygen, nitrogen da sauran iskar gas mara amfani da ke cikin tsarin;
6. Ana amfani da Hafnium sau da yawa a matsayin ƙari a cikin man fetur na hydraulic don hana haɓakar man fetur na hydraulic yayin ayyukan haɗari.Kamar yadda Hafnium yana da ƙarfi anti-volatility, ana amfani dashi gabaɗaya a cikin man hydraulic na masana'antu da man hydraulic na likita;
7. Hakanan ana amfani da sinadarin Hafnium a cikin sabuwar na'ura mai sarrafa ta Intel45nm;
8. Hafnium gami za a iya amfani da a matsayin gaban kariya rufi ga roka nozzles da gliding sake shigar da motocin, da kuma Hf-Ta alloys za a iya amfani da su ƙera kayan aiki steels da juriya kayayyakin.Ana amfani da Hafnium azaman ƙari a cikin allurai masu jure zafi, kamar gami na tungsten, molybdenum, da tantalum.Ana iya amfani da HfC azaman ƙari na carbide da aka yi da siminti saboda babban taurinsa da wurin narkewa.
Samfura masu dangantaka
Muna kuma samar da waya na hafnium da sandar hafnium, barka da shawara!
