Sintering akwan horow a wɔfa so yɛ alumina ceramics ahorow .
Nea edi kan no, sintering kwan a wɔfa so yɛ wim nhyɛso alumina ceramics: nokwarem no, wɔ wim tebea mu no, ɔkwan a wɔfa so yɛ nipadua no nyinaa, saa kwan yi so wɔ sintering ɔhyew no mu no bɛyɛ kɛse kakra, enti ahwehwɛde ahorow a ɛwɔ hɔ ma fononoo no nso yɛ kɛse, na ahoɔden a wɔsɛe no nso yɛ kɛse yiye.
Nea ɛto so abien, sintering kwan a ɛyɛ hyew-Pressed alumina ceramics: ɔhyew no sua sen nea ɛyɛ normal temperature sintering, na sintered products betumi anya wɔ theoretical density 99%, efisɛ hot-pressed sintering no titiriw di dwuma wɔ preforming, anaasɛ powder no tẽẽ loaded wɔ molded, adeyɛ no yɛ mmerɛw.
Nea ɛtɔ so mmiɛnsa, sintering kwan a wɔfa so yɛ anyinam ahoɔden alumina ceramics: kyerɛ sɛ, ceramic embryonic nipadua no wɔ DC electric field no dwumadie ase tẽẽ de wie sintering dwumadie no nyinaa.
Nea ɛto so anan, sintering kwan a ultra-High pressure alumina ceramics: adwuma nyinaa sintering hia ase nhyɛso a ɛboro ɔpehaha pii wim tebea.
Nea ɛto so anum, sintering method of atmosphere alumina ceramics: titiriw ma nneɛma a ɛyɛ den sɛ wɔbɛhyew wɔ mframa mu, sɛnea ɛbɛyɛ a wobesiw ne oxidation ano no, wobetumi de mframa a ɛfata no ahyɛ fononoo no mu de ayɛ wim tebea a wɔhwehwɛ no, na wɔawie sintering no wɔ wim tebea yi mu.
Nneɛma a wɔde yɛ nkuku dodow no ara yɛ fitaa titiriw, na saa ara na ɛte wɔ Alumina dɔte ho. Nanso minnim nea enti a, saa ceramic nneɛma yi akyi bere tenten a wɔde adi dwuma, bɛsakra afi fitaa castings so akɔ light yellow, so ɛyɛ alumina ceramic discoloration?
Nokwarem no, ɛnte saa, nea enti a alumina fitaa no bɛdan kɔkɔɔ a ɛyɛ mmerɛw nkakrankakra, ɔkwan biako so no, ne sɛ bere a owia hann no ayɛ adwuma akyi no, ne mu nneɛma no sesa, na nsakrae yi yɛ nea wontumi nsakra no, enti kɔla no nso bɛsakra.
Ɔkwan foforo so no, ebetumi aba sɛ alumina dɔte no ayɛ nsu, na ɛde alumina a nsu wom aba. Nokwarem no, ɛnyɛ nkuku mu nneɛma nko na ɛwɔ saa su yi, nneɛma afoforo nso benya, enti nea yebetumi ayɛ ara ne sɛ yebedi alumina dɔte a ɛyɛ nwonwa no so denam nneɛma a efi akyi nkɛntɛnso a yɛbɛtew so no so.
