Fine ceramics (advanced ceramics, advanced technical ceramics) - Methods for chemical analysis of zirconium oxide powders (ISO 23739:2021)
This document specifies methods for the chemical analysis of zirconium oxide powders used as the raw material for fine ceramics.
It stipulates the determination methods of the zirconium, aluminium, barium, calcium, cerium, cobalt, gadolinium, hafnium, iron, magnesium, potassium, silicon, sodium, strontium, titanium and yttrium contents in zirconium oxide powders for fine ceramics. The test sample is decomposed by acid pressure decomposition or alkali fusion. Contents of zirconium and yttrium are determined by using either a precipitation and gravimetric method or an inductively coupled plasma–optical emission spectrometry (ICP–OES) method. Contents of aluminium, barium, calcium, cerium, cobalt, gadolinium, hafnium, iron, magnesium, potassium, silicon, sodium, strontium and titanium are determined by using an ICP–OES method.
Hochleistungskeramik - Verfahren zur chemischen Analyse von Zirconiumoxidpulvern (ISO 23739:2021)
Dieses Dokument legt Verfahren für die chemische Analyse von Zirconiumoxidpulvern fest, die als Rohmaterial für Feinkeramik verwendet werden.
Es legt die Verfahren zur Bestimmung der Gehalte von Zirconium, Aluminium, Barium, Calcium, Cer, Kobalt, Gadolinium, Hafnium, Eisen, Magnesium, Kalium, Silicium, Natrium, Strontium, Titan und Yttrium in Zirconiumoxidpulvern für Feinkeramik fest. Die Probe wird durch Säuredruckaufschluss oder Schmelzaufschluss in Lösung gebracht. Die Gehalte von Zirconium und Yttrium werden entweder mittels Fällung und gravimetrischem Verfahren oder mittels optischer Emissionsspektrometrie mit induktiv gekoppeltem Plasma (ICP-OES) bestimmt. Die Gehalte von Aluminium, Barium, Calcium, Cer, Kobalt, Gadolinium, Hafnium, Eisen, Magnesium, Kalium, Silicium, Natrium, Strontium und Titan werden mittels ICP-OES-Verfahren bestimmt.
Céramiques techniques - Méthodes pour l'analyse chimique des poudres d'oxyde de zirconium (ISO 23739:2021)
Le présent document spécifie des méthodes pour l’analyse chimique des poudres d’oxyde de zirconium utilisées comme matières premières pour les céramiques techniques.
Il stipule les méthodes de détermination des teneurs en zirconium, aluminium, baryum, calcium, cérium, cobalt, gadolinium, hafnium, fer, magnésium, potassium, silicium, sodium, strontium, titane et yttrium dans les poudres d’oxyde de zirconium pour les céramiques techniques. L’échantillon pour essai est décomposé par décomposition sous pression acide ou par fusion alcaline. Les teneurs en zirconium et en yttrium sont déterminées en utilisant soit une précipitation et une méthode gravimétrique, soit une méthode par spectrométrie d’émission optique avec plasma à couplage inductif (ICP–OES). Les teneurs en aluminium, baryum, calcium, cérium, cobalt, gadolinium, hafnium, fer, magnésium, potassium, silicium, sodium, strontium et titane sont déterminées par la méthode ICP–OES.
Fina keramika (sodobna keramika, sodobna tehnična keramika) - Preskusne metode za kemične analize praškov cirkonijevega oksida (ISO 23739:2021)
Ta dokument določa metode za kemično analizo finih praškov cirkonijevega oksida, ki se uporabljajo kot surovina za fino keramiko.
Določa metode določanja vsebnosti cirkonija, aluminija, barija, kalcija, cerija, kobalta, gadolinija, hafnija, železa, magnezija, kalija, silicija, natrija, stroncija, titana in itrija v praških cirkonijevega oksida za fino keramiko. Preskusni vzorec se razgradi s kislinsko razgradnjo ali taljenjem. Vsebnost cirkonija in itrija se določi z uporabo metode obarjanja in gravimetrične metode ali metode optične emisijske spektrometrije z induktivno sklopljeno plazmo (ICP-OES). Vsebnost aluminija, barija, kalcija, cerija, kobalta, gadolinija, hafnija, železa, magnezija, kalija, silicija, natrija, stroncija in titana se določi z uporabo metode optične emisijske spektrometrije z induktivno sklopljeno plazmo.
