Thermal conductivity ntawm kua hlau Gallium Indium Tin Alloy
May 19, 2022
Plaub cov kua hlau gallium indium tin alloys (Ga50In25Sn25), (Ga60In25Sn15), (Ga66In20.5Sn13.5), (Ga75In10Sn15) tau npaj los ntawm cov dej da dej cua sov txoj kev ua ke nrog ultrasonic stirring thiab nqus degassing tshuab.
Cov tshuaj muaj pes tsawg leeg thiab qhov ntom ntom ntawm gallium indium tin alloy tau sim los ntawm inductively txuas nrog cov ntshav emission spectrometer thiab cov khoom siv-kua dual-lub hom phiaj ntom ntom ntsuas, raws li. Lub melting point, freezing point, tshwj xeeb tshav kub muaj peev xwm, thermal conductivity thiab thermal diffusivity ntawm gallium indium tin alloy yog yus muaj los ntawm txawv scanning calorimeter. Cov txiaj ntsig tau pom tias qhov ntom ntawm plaub lub gallium indium tin alloys yog 5.4 ~ 6.1 g / cm^(3), cov ntsiab lus melting yog 11.0 ~ 19.8 degree , cov ntsiab lus khov yog -30. 1 ~ 1.2 degree, thiab qhov tshwj xeeb kub muaj peev xwm ntawm 25 degree yog 400 ~ 450 J / (kg· K); Qhov tshwj xeeb kub muaj peev xwm, thermal conductivity thiab thermal diffusivity ntawm eutectic gallium indium tin alloy (Ga66In20.5Sn13.5) zoo dua li cov hlau Cu, qhia tias nws cov cua kub dissipation zoo dua li Cu.
