CAS 12069-85-1 Hafnium Carbide Powder HfC Mtengo Waufa
Dzina la malonda:HfC PowderMtengoHafnium Carbide Powder
Kufotokozera kwa HfC Powder
Hafnium carbide (HfC Powder) ndi gulu la carbon ndi hafnium. Malo ake osungunuka ndi pafupifupi 3900 ° C, yomwe ndi imodzi mwazinthu zowonongeka kwambiri zomwe zimadziwika. Komabe, kukana kwake kwa okosijeni ndikotsika kwambiri, ndipo makutidwe ndi okosijeni amayambira pa kutentha kotsika mpaka 430°C.
HfC ufa ndi wakuda, imvi, wolimba wolimba; mkulu mtanda gawo kuyamwa manyutroni matenthedwe; resistivity 8.8μohm · cm; kwambiri refractory zinthu bayinare kudziwika; kuuma 2300kgf/mm2; amagwiritsidwa ntchito muzitsulo zowongolera nyukiliya; Amakonzedwa ndikuwotcha HfO2 ndi mwaye wamafuta pansi pa H2 pa 1900°C-2300°C. Amagwiritsidwa ntchito ngati crucible kusungunula okusayidi ndi ma oxides ena.

Kugwiritsa ntchito HfC Powder
1. HfC ufa angagwiritsidwe ntchito ngati chowonjezera kwa simenti carbide, chimagwiritsidwa ntchito m'munda wa zida kudula ndi nkhungu;
2. HfC yogwiritsidwa ntchito ku rocket nozzle zakuthupi, ingagwiritsidwe ntchito pamphuno ya roketi, yogwiritsidwa ntchito m'munda wamlengalenga, ndipo ingagwiritsidwe ntchito pamphuno, kutentha kwapamwamba, arc kapena electrode kwa electrolysis;
3. HfC ufa wogwiritsidwa ntchito mu ndodo zowongolera nyukiliya. Ndizitsulo zabwino zopangira ndodo zowongolera makina a nyukiliya;
4.Kugwiritsidwa ntchito pokonzekera zoumba zotentha kwambiri;
5.Reactant popanga hafnium yokhala ndi polima ya organometallic;
6.HfC ufa wogwiritsidwa ntchito popaka.
