He liʻiliʻi ka ʻili o ka flake graphite, ʻaʻohe hemahema ma kahi nui, a aia ma kahi o 0.45% mau mea hoʻohuihui mea hoʻoheheʻe ma luna o ka ʻili o ka flake graphite, ka mea e hoʻohaʻahaʻa i ka wettability o ka flake graphite. Ke hydrophobicity ikaika ma luna o ka ili o ka flake graphite worsens ka fluidity o castable, a me ka flake graphite makemake e aggregate ma mua o ka hoʻopuehu like i loko o ka refractory, no laila ua paʻakikī e hoomakaukau i ka lole a me ka dense amorphous refractory. ʻO ka moʻolelo liʻiliʻi o ka Furuite graphite kānana o ka wettability a me nā palena noi o ka flake graphite:
Flake graphite
ʻO ka microstructure a me nā waiwai o ka flake graphite ma hope o ka sintering wela kiʻekiʻe e hoʻoholo nui ʻia e ka wettability o ka wai silicate kiʻekiʻe i ka flake graphite. I ka wā e hoʻomaʻemaʻe ai, silicate wai ʻāpana ma lalo o ka hana o ka capillary ikaika, i loko o ka ʻāpana ʻāpana, e ka adhesion ma waena o lākou e hoʻopaʻa i nā ʻāpana graphite flake, i ka hoʻokumu ʻana i kahi papa kiʻiʻoniʻoni a puni ka graphite flake, ma hope o ka hoʻoluʻu ʻana e hana i kahi continuum. a me ka hoʻokumu ʻana o ke kiʻekiʻe adhesion interface me ka flake graphite. Inā ʻaʻole pulu ʻia nā mea ʻelua, hoʻohui ʻia nā ʻāpana graphite flake, a paʻa ka ʻāpana wai silicate i ka ʻāpana ʻāpana a hana i kahi kino kaʻawale, he paʻakikī ke hana i kahi paʻakikī paʻakikī ma lalo o ka wela kiʻekiʻe.
No laila, ua hoʻoholo ʻo Furuite graphite e hoʻomaikaʻi ʻia ka pulu o ka flake graphite i mea e hoʻomākaukau ai i nā refractory kalapona maikaʻi loa.
