He liʻiliʻi ka ʻili o ka flake graphite, ʻaʻohe kīnā ma kahi ākea, a aia ma kahi o 0.45% mau mea hoʻohuihui organik volatile ma luna o ka flake graphite, kahi e hōʻino ai i ka makū o ka flake graphite. ʻO ka hydrophobicity ikaika ma luna o ka flake graphite e hoʻopilikia ai i ka wai o ka castable, a ʻo ka flake graphite e hōʻuluʻulu ma mua o ka hoʻopuehu like ʻana i loko o ka refractory, no laila he paʻakikī ke hoʻomākaukau i ka refractory amorphous like a paʻa. ʻO ka moʻo liʻiliʻi o ka loiloi graphite Furuite o ka wettability a me nā palena noi o ka flake graphite:
ʻO ka grafiti ʻōpala
ʻO ke ʻano 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 wela kiʻekiʻe i ka flake graphite. I ka wā e pulu ai, ka pae wai silicate ma lalo o ka hana o ka ikaika capillary, i loko o ka hakahaka ʻāpana, ma o ka hoʻopili ʻana ma waena o lākou e hoʻopaʻa i nā ʻāpana graphite flake, i ka hoʻokumu ʻana o kahi papa o ke kiʻiʻoniʻoni a puni ka flake graphite, ma hope o ka hoʻomaʻalili ʻana e hana i kahi continuum, a me ka hoʻokumu ʻana o kahi interface hoʻopili kiʻekiʻe me ka flake graphite. Inā ʻaʻole pulu nā mea ʻelua, hana nā ʻāpana graphite flake i nā aggregates, a ua kaupalena ʻia ka pae wai silicate i ka hakahaka ʻāpana a hana i kahi kino kaʻawale, he paʻakikī ke hana i kahi paʻakikī paʻakikī ma lalo o ke kiʻekiʻe wela.
No laila, ua hoʻoholo ka graphite Furuite e pono e hoʻomaikaʻi ʻia ka maʻalahi o ka pulu ʻana o ka graphite flake i mea e hoʻomākaukau ai i nā refractories kalapona maikaʻi loa.
