Description

 

Barium carbonate is widely used in the ceramics industry as an ingredient in glazes. It acts as a flux, a matting and crystallizing agent and combines with certain colouring oxides to produce unique colours not easily attainable by other means. It is also used for removing of sulfates in phosphoric acid production and chlorine alkali electrolysis.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Anwendungen
Bariumcarbonat wird in der Keramikindustrie häufig als Inhaltsstoff in Glasuren verwendet. Es fungiert als Flussmittel, als Mattierungs- und Kristallisationsmittel und erzeugt in Kombination mit bestimmten Farboxiden einzigartige Farben, die auf andere Weise nicht leicht zu erreichen sind. Es wird auch zur Entfernung von Sulfaten in der Phosphorsäureproduktion und Chloralkali-Elektrolyse verwendet.

Löslichkeit
Unlöslich in Wasser und Alkohol. Löslich in Essigsäure, Salzsäure und Salpetersäure.
