Potassium borohydride wani fili ne na inorganic. Kaddarorinsa sune kamar haka:
1. Bayyanar: Potassium borohydride shine farin crystalline foda ko granule.
3. Solubility: Potassium borohydride yana narkewa a cikin ruwa kuma a hankali a sanya shi cikin ruwa don samar da hydrogen da potassium hydroxide.
4. Musamman nauyi: Yawan potassium borohydride yana da kusan 1.1 g/cm³.
5. Kwanciyar hankali: A ƙarƙashin yanayi na al'ada, potassium borohydride yana da inganci, amma yana iya rushewa a gaban yawan zafin jiki, zafi mai zafi da karfi mai karfi.
Babban amfani da potassium borohydride sun hada da:
1. Tushen hydrogen: Potassium borohydride za a iya amfani dashi azaman reagent don haɗakar hydrogen, wanda ake samarwa ta hanyar amsawa da ruwa.
1.
3. Metal surface jiyya: Potassium borohydride za a iya amfani da electrolytic hydrogenation magani na karfe saman don rage surface oxides.
Hanyoyin shirye-shiryen potassium borohydride sun haɗa da hanyar rage kai tsaye, hanyar antiborate da hanyar rage foda na aluminum. Daga cikin su, hanyar da aka fi amfani da ita ana samun su ta hanyar amsawar sodium phenylborate da hydrogen a ƙarƙashin aikin mai kara kuzari.
Bayanan aminci na potassium borohydride shine kamar haka:
1. Potassium borohydride yana da ƙarfi mai ƙarfi, kuma ana samar da hydrogen lokacin da yake amsawa da ruwa da acid, don haka yana buƙatar sarrafa shi a wuri mai kyau.
2. A guji hulɗa da fata, idanu, da hanyoyin numfashi don hana haushi da rauni.
3. Lokacin adanawa da amfani da potassium borohydride, ya kamata a kula don hana haɗuwa da oxidants da sauran abubuwa don hana wuta ko fashewa.
4. Kada a haɗa potassium borohydride tare da abubuwan acidic don guje wa samuwar iskar gas mai haɗari.
5. Lokacin zubar da sharar potassium borohydride, yakamata a bi ƙa'idodin muhalli da aminci masu dacewa.
