Ievads kvarca keramikas izstrādājumos

Kvarca keramika, kas pazīstama arī kā kausēta kvarca keramika vai tīra silīcija keramika, ir uzlabots keramikas materiāls, kas izgatavots no tīra silīcija dioksīda (SiO₂). To ražo, kausējot augstas tīrības pakāpes kvarca smiltis augstā temperatūrā un pēc tam atdzesējot un sacietējot. Tam ir unikālas fizikālās un ķīmiskās īpašības, kas padara to par ideālu izvēli daudziem augsto tehnoloģiju lietojumiem. Kvarca keramikas izstrādājumi tiek plaši izmantoti pusvadītāju ražošanā, optikā, elektronikā, ķīmiskajā rūpniecībā un augstas temperatūras rūpniecībā.

Kvarca keramikas īpašības un priekšrocības

Zems termiskās izplešanās koeficients: tā zemā termiskās izplešanās koeficienta dēļ kvarca keramikai ir laba izmēru stabilitāte, mainoties temperatūrai, un to nav viegli deformēt vai plaisāt.

Lieliska elektriskā izolācija: nodrošina izcilu elektriskās izolācijas veiktspēju un ir piemērota lietojumiem, kuriem nepieciešama augstsprieguma izolācija.

Augsta caurspīdīgums: Tam ir laba gaismas caurlaidība plašā diapazonā no ultravioletā līdz infrasarkanajam starojumam, un tas ir īpaši piemērots tādiem lietojumiem kā optiskie logi un lēcas.

Ķīmiskā stabilitāte: Lieliska izturība pret lielāko daļu skābju, sārmu un citu kodīgu vielu, un to gandrīz neietekmē citas ķīmiskās vielas, izņemot fluorūdeņražskābi un fosforskābi.

Mehāniskā izturība: lai gan kvarca keramika nav tik cieta kā daži citi keramikas veidi, tai joprojām ir pietiekami daudz mehāniskās izturības, lai apmierinātu daudzu pielietojuma scenāriju vajadzības.

Augsta UV caurlaidība: tai ir augsta caurlaidība ultravioletajā reģionā, kas padara to ļoti noderīgu UV konservēšanas iekārtās un UV spektrometros.
