Iinkcukacha zeMveliso

Ingcaciso yeMveliso

I-Hafnium powder yintsimbi yesilivere-emhlophe, ngokwezinto ezibonakalayo, i-hafnium powder inezinga eliphezulu lokunyibilika kunye neqondo eliphezulu lokubilisa, indawo yokubilisa i-2545 ° C, indawo yokubilisa yi-3876 ° C. Kwakhona ine-conductivity ephezulu ye-thermal. kunye nokuxhathisa okuphezulu, ngoko ke isetyenziswa rhoqo ekwenzeni i-superalloys kunye namacandelo e-elektroniki.Ngokubhekiselele kwiipropati zeekhemikhali, i-hafnium powder kulula ukusabela ngezinto ezingezona zetsimbi ezifana ne-oksijeni kunye ne-nitrogen ukuvelisa i-oxides ehambelanayo kunye ne-nitrides.Kwakhona yenza i-alloys kunye neentsimbi ezininzi, ezifana ne-hafnium-based alloys.Ngokuphathelele ukusetyenziswa kunye nokubaluleka, i-hafnium powder yinto ebaluleke kakhulu, esetyenziswa ngokubanzi kwi-aerospace, imikhosi, i-electronics kunye nezinye iindawo.Umzekelo, idityaniswe ne-tungsten, i-rhenium kunye nezinye iintsimbi zibe namandla aphezulu, i-alloys esekwe kubushushu obuphezulu be-hafnium ukuze kwenziwe iinjini zenqwelomoya kunye neenjini zerokethi.Ukongeza, i-hafnium powder ingasetyenziselwa ukwenza izinto ze-elektroniki, ezinjenge-capacitors, resistors, njl.

Isicelo

IHafnium Hf powder isetyenziselwa ikakhulu:

1. Ngokuqhelekileyo isetyenziswe kwi-X-ray cathode kunye ne-tungsten wire production;

2. I-hafnium ecocekileyo ineenzuzo zeplastiki, ukucutshungulwa lula kunye nokumelana nokushisa okuphezulu kwe-corrosion, kwaye yinto ebalulekileyo kwishishini lamandla e-athomu;

3. I-Hafnium inecandelo elikhulu lokubamba i-neutron ye-thermal, eyenza ibe yinto efanelekileyo yokuthatha i-neutron, enokusetyenziswa njengentonga yokulawula kunye nesixhobo sokukhusela kwii-athomu ze-athomu;

4. I-Hafnium powder ingasetyenziswa njenge-propellant yeerokethi

5. I-Hafnium ingasetyenziswa njenge-getter kwiinkqubo ezininzi ezivuthayo.I-Hafnium getter inokususa i-oksijini, i-nitrogen kunye nezinye iigesi ezingeyomfuneko ezikhoyo kwinkqubo;

6. I-Hafnium isoloko isetyenziselwa ukongeza kwi-oyile ye-hydraulic ukukhusela i-volatilization yeoli ye-hydraulic ngexesha lemisebenzi enobungozi obukhulu.Njengoko i-Hafnium ine-anti-volatility enamandla, isetyenziswa ngokubanzi kwi-oyile ye-hydraulic ye-industrial kunye neoli ye-hydraulic yonyango;

7. Isixhobo seHafnium sikwasetyenziswa kwiprosesa ye-Intel45nm yamva nje;

8. I-alloys ye-Hafnium ingasetyenziselwa njengengubo yokukhusela yangaphambili ye-rocket nozzles kunye neenqwelo zokungena kwakhona ze-gliding, kunye ne-Hf-Ta alloys ingasetyenziselwa ukuvelisa izixhobo zensimbi kunye nezixhobo zokumelana.I-Hafnium isetyenziswa njengento eyongezayo kwi-alloys ekwazi ukumelana nobushushu, njenge-alloys ye-tungsten, i-molybdenum, kunye ne-tantalum.I-HfC ingasetyenziswa njengesongezelelo se-carbide ngenxa yokuqina kwayo okuphezulu kunye nendawo yokunyibilika.
