Nezve Gallium
Gallium anotonhora pamusoro pehuremu hweimba pa 29.76 degrees C. Inowedzera kana ichi solidifies, semvura. Gallium yaive yakavakirwa na Mendeleev se 'eka-aluminium' pamberi pekuwanikwa kwayo uye ine imwe yeakanyanya marudzi emvura echero metal.
Mashandisiro & Maapplication
Semiconductor compounds (GaAs, GaN), LEDs, laser diodes, solar cells, uye medical thermometers.
Nhoroondo yemitambo
Gallium inotonhora pa 29.76 degrees C, saka inotonhora munzeve dzako. Kune chikonzero chikuru chinokonzera kuti gallium iome mumvura yakasviba.
