Q1:Dɛn ne nneɛma a wɔtaa de yɛ alumina a ɛyɛ alumina a ɛyɛ den?
A1:
High-alumina ceramic materials yɛ ceramic nneɛma bi a alumina (AL2O3) sɛ ade titiriw. wɔtaa kura alumina a ɛdɔɔso na ɛwɔ ɔhyew a ɛkorɔn a ɛko tia, wear resistance, corrosion resistance ne nneɛma afoforo. sɛ nhwɛso no,
Alumina ceramic: alumina ceramic yɛ ceramic ade a alumina yɛ ade titiriw. ɛwɔ ɔhyew a ɛkorɔn a ɛko tia, wear resistance ne nnuru a ɛyɛ den. wɔde di dwuma kɛse wɔ ɛlɛtrɔnik, mfiri, nnuru nnwuma ne mfuw afoforo, te sɛ ɛlɛtrɔnik ceramics, abrasive ceramics, insulating ceramics, etc{2}}.
Aluminum Nitride Ceramic: Aluminum Nitride Ceramic yɛ ceramic ade a aluminum nitride yɛ ne fã titiriw. ɛwɔ ɔhyew a ɛkɔ mu ne anyinam ahoɔden a ɛbɔ ho ban su na ɛfata ma ɔhyew kɛse ɛlɛtrɔnik nneɛma a wɔde kyekyere nneɛma, radiators ne mfuw afoforo.
Zirconia Ceramic: Zirconia ceramic yɛ ceramic adeɛ a ɛwɔ zirconia sɛ adeɛ titire. ɛwɔ ahoɔden a ɛkorɔn, ɛyɛ den a ɛkorɔn ne ɔhyeɛ a ɛkyɛn so. Wɔtaa de di dwuma wɔ nnuruyɛ nnwinnadeɛ, gas sensor, ceramic nnwinnadeɛ ne mfuo foforɔ.
Aluminum Boron Nitride Ceramic: Aluminum Boron Nitride Ceramic yɛ ceramic ade a aluminum nitride ne boron aluminum nitride yɛ ne nneɛma atitiriw. ɛwɔ ɔhyew a ɛkɔ mu ne nnuru a ɛyɛ den na wɔtaa de di dwuma wɔ ɔhyew a ɛkorɔn mu, nneɛma a wɔde kyekyere nneɛma ne mfuw afoforo{2}}
alumina ceramic fiber: alumina ceramic fiber yɛ fiber ade a alumina yɛ ade titiriw. Ɛwɔ su pa te sɛ hann mu duru, ahoɔden a ɛkorɔn ne ɔhyew a ɛkorɔn a ɛko tia. Wɔtaa de di dwuma wɔ mmeae a ɔhyew a ɛkɔ soro ɔhyew a ɛbɔ ho ban, nnyigyei a ɛbɔ ho ban ne ɔhyew a wɔkora so{2}}
Magnesium Aluminum Spinel Ceramic: Magnesium Aluminum Spinel Ceramic yɛ ceramic ade a magnesium oxide ne alumina yɛ ne nneɛma titiriw. ɛwɔ ɔhyew a ɛko tia ne nnuru a ɛyɛ den na wɔtaa de di dwuma wɔ refractory applications. nneɛma, ɛlɛtrɔnik mfiri ne mmeae afoforo.
