1. ʻO ke kūpaʻa wela kiʻekiʻe, ka helu heheʻe 3850 ± 50 ° C, ka helu hoʻolapalapa 4250.
2. Haʻahaʻa haʻahaʻa lehu, maʻemaʻe kiʻekiʻe, e pale i ka contamination o kāu huahana.
3. He mea maʻalahi ka graphite e hana i kekahi ʻano āu e makemake ai.
4. Ka ikaika mechanical kiʻekiʻe
5. He hana hoʻoheheʻe maikaʻi
6. Kiʻekiʻe thermal conductivity
7. Kiʻekiʻe thermal haʻalulu kū'ē a me ka kemikala kū'ē
8. Kiʻekiʻe corrosion kū'ē a me ka oxidation kū'ē
9. maikaʻi conductivity
10. Kiʻekiʻe kiʻekiʻe a me ka ikaika mechanical kiʻekiʻe
11. He liʻiliʻi loa ka coefficient o ka hoʻonui ʻana i ka wela, a loaʻa iā ia kekahi mau ʻano pale no ka hoʻoilo wikiwiki a me ka wela.
12. He kūpaʻa koʻikoʻi ko nā pahu kuʻi graphite a me ka paʻa kemika maikaʻi loa no nā hopena ʻakika a me ka alkaline. No laila, ʻaʻole ia e komo i nā hopena kemika i ka wā o ka hoʻoheheʻe ʻana.
13. He laumania ka paia o loko o ka graphite crucible. ʻAʻole maʻalahi ka hoʻoheheʻe ʻana i ka wai metala a pili paha i ka paia o loko o ka crucible, no laila he kahe maikaʻi a me ka hiki ke ninini.
