Product Description

Hafnium powder isimbi-chena simbi, maererano nemaitiro emuviri, hafnium powder ine nzvimbo yakakwirira yekunyunguduka uye nzvimbo yakakwirira yekubikira, iyo inonyunguduka ndiyo 2545 ° C, iyo inopisa ndeye 3876 ° C. Iinewo high thermal conductivity. uye yakakwirira resistivity, saka inowanzoshandiswa mukugadzira superalloys uye zvigadzirwa zvemagetsi.Panyaya yemakemikari ehupfumi, hafnium powder iri nyore kuita neasina-metallic zvinhu zvakadai seokisijeni uye nitrogen kuti ibudise oxides uye nitrides zvinoenderana.Inoumbawo alloys ane simbi dzakawanda, senge hafnium-based alloys.Panyaya yekushandiswa uye kukosha, hafnium powder chinhu chakakosha zvikuru, chinoshandiswa zvakanyanya mumhepo, mauto, magetsi uye mamwe minda.Semuenzaniso, inogadzirwa ne tungsten, rhenium nedzimwe simbi kuita yakakwirira-simba, yakakwirira-yekushisa inodzivirira hafnium-based alloys yekugadzira injini dzendege uye rocket injini.Mukuwedzera, hafnium powder inogona kushandiswawo kugadzira zvinhu zvemagetsi, zvakadai se capacitors, resistors, nezvimwe.

Application

Hafnium Hf hupfu inonyanya kushandiswa ku:

1. Inowanzoshandiswa mu X-ray cathode uye tungsten wire kugadzira;

2. Pure hafnium ine zvakanakira zvepurasitiki, nyore kugadzirisa uye yakakwirira tembiricha corrosion resistance, uye chinhu chakakosha muindasitiri yesimba reatomu;

3. Hafnium ine chikamu chikuru chekupisa neutron kutora chikamu, zvichiita kuti ive yakakodzera neutron absorber, iyo inogona kushandiswa sechinhu chinodzora uye chidziviriro chekudzivirira mune atomic reactors;

4. Hafnium powder inogona kushandiswa sepropellant yemaroketi

5. Hafnium inogona kushandiswa sechigadziro kune dzakawanda inflatable systems.Hafnium getter inogona kubvisa okisijeni, nitrogen uye mamwe magasi asingakoshi aripo muhurongwa;

6. Hafnium inowanzoshandiswa sechinhu chinowedzera mu hydraulic mafuta kudzivirira kupisa kwemafuta e hydraulic panguva yekushanda kwepamusoro-ngozi.Sezvo Hafnium ine yakasimba anti-volatility, inowanzoshandiswa muindasitiri hydraulic oiri uye yekurapa hydraulic oiri;

7. Hafnium element inoshandiswawo mune yazvino Intel45nm processor;

8. Hafnium alloys inogona kushandiswa sepamberi yekudzivirira yekudzivirira ye rocket nozzles uye gliding re-entry mota, uye Hf-Ta alloys inogona kushandiswa kugadzira simbi yezvishandiso uye yekupikisa zvinhu.Hafnium inoshandiswa sechinhu chinowedzera mumagetsi asingadziviriri kupisa, senge alloys ye tungsten, molybdenum, uye tantalum.HfC inogona kushandiswa sesemented carbide yekuwedzera nekuda kwekuoma kwayo kwakanyanya uye nzvimbo yekunyungudika.
