Mumunda wekugadzirwa kwemaindasitiri, zvinhu zveceramic zviri kunyora ngano nyowani. Kusiyana nemidziyo yeceramic muhupenyu hwezuva nezuva, maindasitiri eceramics aratidza kushanda kwawo kwakatanhamara munzvimbo dzakakosha dzakadai sesimbi, engineering yemakemikari, uye simba idzva. Aluminium oxide, silicon nitride, zirconium oxide uye zvimwe zvinhu zvine hunhu hwazvo, asi kana zvasvika pakusimba kwakasimba kwakazara kwe "all-around player",silicon carbide ceramicshapana mubvunzo kuti akanakisa.
Alumina ceramics akafanana nemhizha dzechinyakare, dzinozivikanwa nekuoma kwazvo uye kugona kugona, asi dzinowanzokurirwa nekupisa kwakanyanya. Silicon nitride ceramics, senge midziyo chaiyo, ine yakanakisa yekupisa kuvhunduka, asi inogona kuratidza "mbabvu dzakapfava" mune dzimwe nzvimbo dzinoparadza. Zirconia ceramics dzakafanana nemauto akasarudzika, anozivikanwa nekuomarara kwazvo, asi vanogona "kurega" kutanga mukupisa kwakanyanya uye kwenguva refu hondo.
Kusiyana neizvi, silicon carbide ceramics yakaratidza kunoshamisa kusimba kwesimba. Iyi crystal zvinhu, iyo yakanyatsovakwa nesilicon kabhoni maatomu, ane mabhenefiti matatu akakosha: kusimba kwayo kwakanyanya kupisa kunoita kuti irambe "yakadzikama" munzvimbo dzine tembiricha, kusapfeka kwayo kwakanaka kunoita kuti "iwedzere kushinga" mumamiriro ekushanda akaomarara, uye kugadzikana kwayo kwekemikari kwakafanana nenhoo yekudzivirira yakasikwa, inopesana nekupinda kwenhau dzakasiyana siyana.
Mumunda wekutonga kwekupisa, iyo yekupisa conductivity yesilicon carbide ceramics yakapetwa katatu iyo yesimbi yakajairwa. Iri rekuzvarwa "tarenda rekupisa kupisa" rinoita kuti ive sarudzo yakanaka kune yakakwirira-tembiricha kilns uye semiconductor substrates. Yakatarisana nedambudziko rekupfeka uye kubvaruka, kuoma kwayo kwepamusoro ndekwechipiri chete kune madhaimani, kuratidza hupenyu hwesevhisi hurefu mumamiriro ezvinhu akadai semuchina wemigodhi nemapombi ekufambisa. Chinotonyanya kushomeka ndechekuti chinyorwa ichi chinogona kuchengetedza ruvara rwayo rwechisikigo kunyangwe munzvimbo dzinotyisa senge yakasimba acids, ichinyatso kuenderana nezvinodiwa zvakakosha zvemichina yemakemikari.
Nekusimudzira kwakasimba kweindasitiri yesimba idzva, silicon carbide ceramics iri kuvhura nzvimbo nyowani dzekushandisa. Mumunda we photovoltaic simba rekugadzira, inova yakanakisa mamiriro ekunze anopikisa rutsigiro zvinhu; Paiyo lithium bhatiri yekugadzira mutsara, yakashandurwa kuita yakakwirira-chaiyo sintered mahwendefa. Kugona uku "kuyambuka-muganho" kunobva mukusanganiswa kwayo kwakasiyana-siyana - kunogona kutsungirira tembiricha yakadzikama ye1350 ℃ uye kushanda zvakatsiga munzvimbo dzinotonhora zvakanyanya dze -60 ℃.
Senyanzvi dzehunyanzvi dzakabatanidzwa zvakanyanya mumunda wesilicon carbide ceramics, isu tinoramba tichikwenenzvera magadzirirwo emidziyo uye sintering maitiro, tichichengeta zvakanakira zvechinyakare, tichigara tichivandudza simba remakanika uye kurongeka kwechokwadi kwezvinhu. Kuburikidza neiyo chaiyo mbishi reshiyo uye innovative sintering tekinoroji, zvigadzirwa zvedu zvakavandudza kuvimbika pasi pemamiriro ekushanda akaomarara, zvichipa vimbiso yakasimba yemidziyo yemazuva ano maindasitiri.
Kusarudza maindasitiri eceramic zvinhu kuri kutsvaga chiyero pakati pekuita uye mutengo. Silicon carbide ceramics, ine zvakanakira mutengo-inoshanda zvakanaka, iri kutsanangudza zviyero zvekugadzirwa kwemaindasitiri - kuderedza kutsiva frequency nehupenyu hurefu, kudzikisa mutengo wekugadzirisa nekuita kwakadzikama, uye kurerutsa kusarudzwa kwemidziyo nehuwandu hwakawanda hwekushandisa. Ichi chinogona kunge chiri chikonzero chechikonzero nei mainjiniya akawanda achinyora sechinhu chinodiwa.
Kana tichitaura nezve kufambira mberi kwemaindasitiri, kuvandudzwa kwezvinhu kazhinji ndiyo inonyanya kukosha uye yakakosha budiriro. Iko kuenderera mberi kwekushanduka kwesilicon carbide ceramics haingomiriri budiriro mutekinoroji yeceramic, asi zvakare inosheedzera kumwe kusvetuka mukugadzirwa kwemaindasitiri. Munguva ino yekutsvaga kuita kwekupedzisira, iyi "yekufunga" ceramic zvinhu iri kuvhura nzvimbo itsva yekufungidzira yekugadzirwa kwemazuva ano.
