\"TuboEl tubo de zafiro EFG (Edge-Defined Film-Fed Growth) es un componente hueco de alto rendimiento fabricado con \u00f3xido de aluminio monocristalino (Al\u2082O\u2083). A diferencia del mecanizado tradicional a partir de bolas cultivadas en KY, el m\u00e9todo EFG permite un crecimiento casi en forma de red, lo que reduce significativamente el desperdicio de material y los costes de mecanizado.<\/p>\n

Con propiedades excepcionales como una dureza extrema (Mohs 9), resistencia a altas temperaturas (>2000\u00b0C), excelente transmisi\u00f3n \u00f3ptica (190 nm - 5 \u03bcm) y una estabilidad qu\u00edmica superior, los tubos de zafiro se utilizan ampliamente en entornos exigentes en los que el cuarzo o el vidrio no pueden funcionar con fiabilidad.<\/p>\n

                  P1: \u00bfQu\u00e9 es un tubo de zafiro?
                  Un tubo de zafiro es un componente cil\u00edndrico hueco fabricado con Al\u2082O\u2083 monocristalino, que ofrece una dureza, estabilidad t\u00e9rmica y transparencia \u00f3ptica excepcionales.<\/p>\n

                  P2: \u00bfCu\u00e1l es la ventaja de los tubos de zafiro EFG?
                  Los tubos EFG se cultivan directamente para darles forma, lo que reduce el coste y permite mayores longitudes en comparaci\u00f3n con los m\u00e9todos KY tradicionales.<\/p>\n

                  P3: \u00bfPueden proporcionar tama\u00f1os personalizados?
                  S\u00ed, se pueden personalizar totalmente las dimensiones, las tolerancias, el acabado superficial y la orientaci\u00f3n de los cristales.<\/p>","protected":false},"excerpt":{"rendered":"
