Hafnium tetrachloride, inozivikanwawo sehafnium(IV) chloride or HfCl4, ikomboni ine nhamba yeCAS13499-05-3. Iyo inoratidzirwa nekuchena kwepamusoro, kazhinji 99.9% kusvika 99.99%, uye pasi zirconium content, ≤0.1%. Ruvara rwehafnium tetrachloride particles rinowanzova jena kana kuti chena, ine density ye3.89 g/cubic centimeter uye panonyungudika i432°C. Zvinonyanya kukosha, inoputsika mumvura, zvichiratidza kuti inopindirana nehunyoro.
Hafnium tetrachlorideinogona kushandiswa seyakatangira mukugadzirwa kweyakanyanya-yakakwirira tembiricha ceramics. Inozivikanwa nekugadzikana kwayo kwakanakisa kwekushisa, idzi ceramics dzinoshandiswa mumhando dzakasiyana-siyana dzepamusoro-tembiricha, senge tembiricha yekudzivirira muindasitiri yeaerospace uye kugadzirwa kwemidziyo yekucheka uye crucibles. Kugona kwekomboni kutsungirira kupisa kwakanyanya kunoita kuti ive chinhu chakakosha mukugadzirwa kwezvinhu zvehunyanzvi hwepamusoro uye kushandiswa kwemaindasitiri.
Uyezve,hafnium tetrachlorideinoita basa rakakosha mumunda we-high-power LEDs. Inoshandiswa mukugadzirwa kwephosphors, iyo inokosha pakushanda kwe LEDs. Phosphors zvinhu zvinoburitsa mwenje kana zvakafumurwa nemwaranzi uye zvakabatanidzwa nekuita kwe LED nekushandura mwenje webhuruu kuva mamwe mavara, nekudaro kuvandudza kushanda kwese uye ruvara rwemhando yemwenje.
High-kuchenahafnium tetrachlorideinogona kugadzirwa kudzikisa zirconium yemukati kusvika 200ppm, kuve nechokwadi kuti yakakodzera kune inodiwa maapplication uko kusvibiswa kunogona kukanganisa chigadzirwa chekupedzisira. Iyi nhanho yekuchena yakakosha kune yakabudirira synthesis yezvinhu zvepamberi, uko kurongeka chaiko kwemakemikari kuumbwa kwakakosha.
Muchidimbu,hafnium tetrachloride, nekuchena kwayo kwakanakisa uye yakasarudzika zvimiro, yave yakakosha precursor yekugadzirwa kweyepamusoro-yepamusoro tembiricha ceramics uye inoita basa rakakosha mukufambisira mberi kwesimba-simba re LED tekinoroji. Hurukuro hwayo uye kuita zvekare kunoita kuti ive chinhu chakakosha mukugadzirwa kwezvinhu zvekucheka-kumucheto maindasitiri uye tekinoroji application.
