Hafnium diboride
CAS 12007-23-7
Molecular fomula B2Hf
Iyo molekyuli uremu ndeye 200.112

Main maficha:

Hafnium diboride (HfB2) ndeye grey nhema kristaro ine metallic kubwinya. Yakagadzirwa sekristaro ndeye hexagonal system. Seyakanakisa Ultra-yakakwira tembiricha zvedongo zvinhu,

HfB2 ine nzvimbo yakanyunguduka yakakwira (3380 ℃), yakachena kuchena, diki diki saizi, kugoverwa yunifomu, yakakura yakatarwa nzvimbo nzvimbo, yakakwira nzvimbo yekuita, yakaderera huwandu hwakawanda, yakakwira magetsi conduction uye yakagadzikana kemikari zvivakwa. Iyo haigadzirise neese makemikari reagents kunze kweiyo HF pane tembiricha yemukati. Zvitsva zvedongo zvigadzirwa zvine yakanyanya kusungunuka poindi, yakanyanya kudziya conductivity uye oxidation kuramba

Main inoshandisa:

Inonyanya kushandiswa mu-Ultra-yakakwira tembiricha ceramics, mhino koni yeiyo inomhanya-mhanya ndege, avhiyesheni, muchadenga uye mimwe minda. Iyo ndiyo inogona kwazvo kukwikwidza zvinhu zve Ultra-yakakwira tembiricha ceramics. Iyo inowanzo shandiswa se anti anti ablation zvinhu mune yakanyanya-tembiricha oxidation nharaunda, uye ine hunhu hwekukwirira kuomarara, yakakwira modulus, yakakwira yekushisa yekudzivirira uye yakakwira conductivity.
