Zur Gew\u00e4hrleistung eines sicheren Betriebs und zur Verl\u00e4ngerung der Ger\u00e4telebensdauer empfehlen wir, die Verwendung von PBN auf Temperaturen von nicht mehr als 1300\u00b0C zu begrenzen, mit einer kontrollierten Abk\u00fchlungsrate von weniger als 25\u00b0C pro Minute unterhalb von 660\u00b0C. Der Tiegel sollte zwischen jeder Verwendung inspiziert und bei Anzeichen von Rissbildung sofort ersetzt werden.<\/strong><\/p>","protected":false},"excerpt":{"rendered":"
