Fine ceramics (advanced ceramics, advanced technical ceramics) - Methods for chemical analysis of high purity barium titanate powders (ISO 21813:2019)
ISO 21813 specifies methods for the chemical analysis of fine high purity barium titanate powders used as the raw material for fine ceramics.
ISO 21813 stipulates the determination methods of the barium, titanium, aluminium, cadmium, calcium, cobalt, dysprosium, iron, lead, magnesium, manganese, nickel, niobium, potassium, silicon, sodium, strontium, vanadium, zirconium, carbon, oxygen and nitrogen contents in high purity barium titanate powders. The barium and titanium contents, the major elements, are determined by using an acid decomposition-gravimetric method or an acid decomposition-inductively coupled plasma-optical emission spectrometry (ICP-OES) method. The aluminium, cadmium, calcium, chromium, cobalt, dysprosium, iron, lead, magnesium, manganese, nickel, niobium, potassium, silicon, strontium, vanadium and zirconium contents are simultaneously determined via an acid digestion-ICP-OES method. The nitrogen content is determined by using an inert gas fusion-thermal conductivity method, while that of oxygen is determined via an inert gas fusion-IR absorption spectrometry method. Finally, the carbon content is determined using a combustion-IR absorption spectrometry method or a combustion-conductometry method.
Hochleistungskeramik - Verfahren zur chemischen Analyse von hochreinen Bariumtitanatpulvern (ISO 21813:2019)
Dieses Dokument legt Verfahren für die chemische Analyse von feinen, hochreinen Bariumtitanatpulvern fest, die als Rohmaterial für Hochleistungskeramiken verwendet werden.
Dieses Dokument legt die Verfahren zur Bestimmung des Barium-, Titan-, Aluminium-, Cadmium-, Calcium-, Cobalt-, Dysprosium-, Eisen-, Blei-, Magnesium-, Mangan-, Nickel-, Niob-, Kalium-, Silicium-, Natrium-, Strontium-, Vanadium-, Zirkonium-, Kohlenstoff-, Sauerstoff- und Stickstoffgehaltes in hochreinen Bariumtitanatpulvern fest. Der Barium und Titangehalt, die wesentlichen Elemente, werden mithilfe eines gravimetrischen Verfahrens mit Säureaufschluss oder eines Verfahrens mit Säureaufschluss kombiniert mit optischer Emissionsspektrometrie mit induktiv gekoppeltem Plasma (en: inductively coupled plasma optical emission spectrometry, ICP-OES) bestimmt. Die Aluminium-, Cadmium-, Calcium-, Chrom-, Cobalt-, Dysprosium-, Eisen-, Blei-, Magnesium-, Mangan-, Nickel-, Niob-, Kalium-, Silicium-, Strontium-, Vanadium- und Zirkoniumgehalte werden simultan mithilfe einem Verfahren von Säureaufschluss mit ICP-OES bestimmt. Der Stickstoffgehalt wird mithilfe eines -Inertgasschmelzverfahrens mit Wärmeleitfähigkeitsdetektion bestimmt, während der Sauerstoffgehalt mithilfe eines Inertgasschmelzverfahrens mit IR-Absorptionsspektroskopie bestimmt wird. Der Kohlenstoffgehalt wird abschließend mithilfe eines Verbrennungs-IR-Absorptionsspektrometrieverfahrens oder eines Verbrennungs-Konduktometrie-Verfahrens bestimmt.
Céramiques techniques - Méthodes d’analyse chimique des poudres de titanate de baryum à haute pureté (ISO 21813:2019)
Le présent document spécifie des méthodes d'analyse chimique de poudres fines de titanate de baryum de haute pureté utilisées comme matière première pour les céramiques techniques.
Le présent document spécifie les méthodes de détermination des teneurs en baryum, titane, aluminium, cadmium, calcium, cobalt, dysprosium, fer, plomb, magnésium, manganèse, nickel, niobium, potassium, silicium, sodium, strontium, vanadium, zirconium, carbone, oxygène et azote dans les poudres de titane de baryum de haute pureté. Les teneurs en baryum et en titane (les éléments principaux) sont déterminées au moyen d’une méthode par gravimétrie après décomposition en milieu acide ou d’une méthode par spectrométrie d’émission optique à plasma induit (ICP-OES) après décomposition en milieu acide. Les teneurs en aluminium, cadmium, calcium, chrome, cobalt, dysprosium, fer, plomb, magnésium, manganèse, nickel, niobium, potassium, silicium, strontium, vanadium et zirconium sont déterminées simultanément au moyen d’une méthode par ICP-OES après minéralisation en milieu acide. La teneur en azote est déterminée à l’aide d’une méthode par conductivité thermique après fusion sous gaz inerte, tandis que celle de l’oxygène est déterminée en utilisant une méthode par spectrométrie d’absorption infrarouge après fusion sous gaz inerte. Enfin, la teneur en carbone est déterminée au moyen d'une méthode par spectrométrie d’absorption infrarouge après combustion ou d’une méthode par conductométrie après combustion.
Fina keramika (sodobna keramika, sodobna tehnična keramika) - Metode za kemijsko analizo praškov barijevega titanata visoke čistosti (ISO 21813:2019)
Standard ISO 21813 določa metode za kemijsko analizo finih praškov barijevega titanata visoke čistosti, ki se uporabljajo kot surovina za fino keramiko.
Standard ISO 21813 določa metode za določevanje vsebnosti barija, titana, aluminija, kadmija, kalcija, kobalta, disprozija, železa, svinca, magnezija, mangana, niklja, niobija, kalija, silicija, natrija, stroncija, vanadija, cirkonija, ogljika, kisika in dušika v praških barijevega titanata visoke čistosti. Vsebnost barija in titana – glavnih elementov – se določi z uporabo gravimetrične metode v kombinaciji s kislinsko razgradnjo ali metode optične emisijske spektrometrije z induktivno sklopljeno plazmo (ICP-OES) v kombinaciji s kislinsko razgradnjo. Vsebnost aluminija, kadmija, kalcija, kroma, kobalta, disprozija, železa, svinca, magnezija, mangana, niklja, niobija, kalija, silicija, stroncija, vanadija in cirkonija se hkrati določi z uporabo metode optične emisijske spektrometrije z induktivno sklopljeno plazmo v kombinaciji z razklopom v kislini. Vsebnost dušika se določi z uporabo metode toplotne prevodnosti v kombinaciji s fuzijo inertnega plina, vsebnost kisika pa z metodo IR-absorpcijske spektrometrije v kombinaciji s fuzijo inertnega plina. Vsebnost ogljika se določi z uporabo metode IR-absorpcijske spektrometrije v kombinaciji z zgorevanjem ali metode konduktometrije v kombinaciji z zgorevanjem.
