Izingxenye ze-Alumina Ceramic

I-Alumina (Al2O3)

I-Alumina ceramics yinto esetshenziswa kakhulu ye-ceramic. Inikeza amandla aphezulu womshini, ukufakwa kukagesi, ukugcinwa kwemvamisa ephezulu, ukuqhutshwa okushisayo, ukumelana nokushisa nokumelana nokugqwala.
Izinto ze-Alumina ceramic zisetshenziswa ezinhlobonhlobo zezicelo ezinjenge-elekthronikhi, izingxenye zepompo nezinzwa zezimoto.
Siphakela okuhlukahlukene kwe-alumina ceramics yokuqukethwe kwe-alumina kusuka ku-80% kuye ku-99.9%
Izakhiwo zomzimba, ukuma, ubukhulu nokubekezelelana njengoba kudingeka.

Izakhiwo ezijwayelekile zomzimba ze-Alumina Ceramics:

Ukufakwa kahle kukagesi
Amandla aphezulu emishini
Ukuqina okuphezulu
Ukuzinza okuhle kakhulu kokushisa
Ukuzinza okuhle kwamakhemikhali
Ukumelana nokugqoka okuhle kakhulu
Ukumelana nokugqwala okuhle kakhulu
Okuphansi kwe-dielectric njalo
Ukumelana nokushisa okuhle.

Imikhiqizo ejwayelekile ye-Alumina Ceramic:

Izingxenye ze-Zirconia Ceramic

I-Zirconia (ZrO2)

I-Zirconia ceramics yinto eqine futhi enzima kunazo zonke phakathi kobumba obuthuthukisiwe.
IZirconia (ZrO2) inesakhiwo se-monoclinic crystal emazingeni okushisa egumbi, kepha iyaguquka
ezakhiweni ezingama-cubic kanye ne-tetragonal emazingeni okushisa aphakeme. Lolu shintsho lungaholela ku-
ukuthuthukiswa kwengcindezi ngesikhathi sokupholisa okunomthelela omubi emandleni ento leyo.

Uhlobo Zirconia Ceramics:

  1. Izici ze-Yttria Ezinzile i-Zirconia ceramics: Izinga lokusebenza lisebenza kufika ku-2100 ℃; ukuminyana okuphezulu, ukuqhuba okuphansi kokushisa; i-inert yamakhemikhali; ukuncibilika kwensimbi; ukuqhutshwa kwe-ion; gqoka ukumelana, ukuqina okuphezulu, ukuqina okuphezulu kokuqhekeka;
  2. Izici ze-Cerium Stabilized Zirconia ceramics: Amazinga okusebenza afinyelela ku-2100 ℃; ukuminyana okuphezulu, ukuqhuba okuphansi kokushisa; i-inert yamakhemikhali; ukumelana nokuncibilika kwensimbi; gqoka ukumelana, ukuqina okuphezulu, ukuqina okuphezulu kokuqhekeka;
  3. Izici ze-Magnesium Stabilized Zirconia ceramics: Izinga lokusebenza lisebenza kufika ku-2400 ℃; ukuminyana okuphezulu, ukuqhuba okuphansi kokushisa; i-inert yamakhemikhali; ukumelana nokuncibilika kwensimbi; gqoka ukumelana, ukuqina okuphezulu, ukuqina okuphezulu kokuqhekeka.

Izakhiwo ezijwayelekile zomzimba zeZirconia Ceramics:

Ubulukhuni be-1.High, ukuqina okuphezulu, amandla okugoba okuphezulu, ukuqina kwe-zirconia ceramic ngu-5.95-6.05g / cm3, ukuqina kwe-zirconia ceramic ngu-8MPa · m1 / 2 noma ngaphezulu;

2.High bafake ukumelana, ongaphakeme ingxabano ilingana , isibuko ebusweni, bushelelezi ngokweqile, ne-coefficient ephansi yokungqubuzana;

3.Good ukwahlukanisa, ukugqwala ukumelana, akukho ugesi static, lokushisa eliphezulu ukumelana, omuhle kakhulu ukwahlukanisa ezishisayo, ezishisayo ukwanda Coefficient useduze ukuthi zensimbi;

  1. I-Zirconia ceramics ine-self-lubrication, ingaxazulula ukungcoliswa okubangelwa indawo yokuthambisa nokuphazamiseka okubangelwa ukondla.

Imikhawulo yokusebenza kwe-Zirconia Ceramic:

Ukwakhiwa kwamakhemikhali: ZRO2≥94.5%
Ubuningi: 6g / cm3
Sintering lokushisa: 1550 ~ 2600 ° C
Amandla we-Breakdown voltage: 15 kV / mm
Ukumuncwa kwamanzi: <0.01% Amandla wokucindezela: 5000 MPa Ubulukhuni: ≥88 (Hra) Ukumelana nevolumu:> 1012 cm
Amandla okugoba: 1100 MPa
I-coefficient yokwanda kwe-Thermal: 6.9 ~ 10 x10 ^ (- 6) / k
Ukuqhuba kokushisa: 2.5 W / mk
Ukumelana nokushisa: 1800 ° C

Imikhiqizo ejwayelekile ye-Zirconia Ceramic:

I-Zirconia ceramics isetshenziswa kakhulu kumadivayisi anamandla amakhulu, amashubhu we-IC MOS, i-IGBT chip-type thermal insulation, amandla amvamisa kakhulu, ukuxhumana, imishini yemishini, amandla aphezulu manje, amandla aphezulu wegesi, izinga lokushisa okuphezulu nezinye izingxenye ezidinga ukuqhutshwa kokushisa nokufakwa okushisayo .
