ʻO ka fiber seramika kahi mea hoʻomehana wela kuʻuna i hoʻohana nui ʻia i nā ʻoihana e like me ka metallurgy, mīkini, uila, keramika, aniani, kemika, kaʻa, ke kūkulu ʻana, ka ʻoihana māmā, ke kūkulu moku koa, a me ka aerospace. Ma muli o ke ʻano a me ka haku mele ʻana, hiki ke hoʻokaʻawale ʻia ka fiber seramika i nā ʻano nui: nā fibers kūlana aniani (amorphous) a me nā fibers polycrystalline (crystalline).
1. Ke ʻano hana no nā olonā mokuʻāina aniani.
ʻO ke ʻano hana o nā olonā keramika aniani e pili ana i ka hoʻoheheʻe ʻana i nā mea maka i loko o kahi umu pale uila. Ke kahe nei ka mea hoʻoheheʻe wela kiʻekiʻe ma o kahi puka i luna o kahi pahu wili wikiwiki o ka centrifuge multi-roller. ʻO ka ikaika centrifugal o ka pahu wili e hoʻolilo i ka mea hoʻoheheʻe wela kiʻekiʻe i mea ʻano olonā. Hiki ke hana ʻia ka mea hoʻoheheʻe wela kiʻekiʻe i mea ʻano olonā ma ka puhi ʻia ʻana me ke kahe ʻana o ka ea wikiwiki.
2 Ke ʻano hana hana fiber Polycrystalline
Aia ʻelua mau ʻano hana o ka polycrystallinenā olonā keramika: ke ʻano colloid a me ke ʻano precursor.
ʻAno Colloidal: hana i nā paʻakai alumini hiki ke hoʻoheheʻe ʻia, nā paʻakai silicon, a me nā mea ʻē aʻe i loko o kahi hopena colloidal me kahi viscosity, a laila hoʻokumu ʻia ke kahawai o ka hopena i loko o nā olonā ma ka puhi ʻia ʻana e ka ea i hoʻopaʻa ʻia a i ʻole ka milo ʻana e ka disk centrifugal, a laila hoʻololi ʻia i loko o nā kristal alumini-silicon oxide fibers ma o ka mālama wela kiʻekiʻe.
ʻAno hana mua: E hana i ka paʻakai alumini hiki ke hoʻoheheʻe ʻia a me ka paʻakai silicon i loko o kahi hopena colloidal me kahi viscosity, e hoʻopili like i ka hopena colloidal me kahi mua (fiber organik i hoʻonui ʻia), a laila e hana i ka mālama wela e hoʻololi i loko o ke aniani kristal alumini-silicon oxide.
