\"DeDe EFG (Edge-Defined Film-Fed Growth) saffierbuis is een hoogwaardige holle component gemaakt van \u00e9\u00e9nkristal aluminiumoxide (Al\u2082O\u2083). In tegenstelling tot traditionele bewerking uit KY-gegroeide boules, maakt de EFG-methode groei in bijna-netvorm mogelijk, waardoor materiaalafval en bewerkingskosten aanzienlijk worden verminderd.<\/p>\n

Met uitzonderlijke eigenschappen zoals extreme hardheid (Mohs 9), bestendigheid tegen hoge temperaturen (>2000\u00b0C), uitstekende optische transmissie (190 nm - 5 \u03bcm) en superieure chemische stabiliteit worden saffierbuizen veel gebruikt in veeleisende omgevingen waar kwarts of glas niet betrouwbaar kunnen presteren.<\/p>\n

                  V1: Wat is een saffierbuis?
                  Een saffieren buis is een holle cilindrische component gemaakt van eenkristal Al\u2082O\u2083, die een uitzonderlijke hardheid, thermische stabiliteit en optische transparantie biedt.<\/p>\n

                  V2: Wat is het voordeel van EFG-saffierbuizen?
                  EFG-buizen worden direct in vorm gekweekt, wat de kosten drukt en langere lengtes mogelijk maakt in vergelijking met traditionele KY-methoden.<\/p>\n

                  V3: Kunt u aangepaste maten leveren?
                  Ja, volledige aanpassing is mogelijk voor afmetingen, toleranties, oppervlakteafwerking en kristalori\u00ebntatie.<\/p>","protected":false},"excerpt":{"rendered":"
