Wasserfreies Borax

Beschreibung:
Wasserfreies Borax, auch bekannt als Natriumborat oder Borax, ist ein weißer, kristalliner Feststoff, der hauptsächlich aus Natrium, Bor, Sauerstoff und Wasserstoff besteht. Seine chemische Formel ist Na2B4O7, und er zeichnet sich durch seine hohe Löslichkeit in Wasser aus, was ihn in verschiedenen Anwendungen nützlich macht. Wasserfreies Borax ist hygroskopisch, was bedeutet, dass es Feuchtigkeit aus der Umgebung aufnehmen kann, was seine Stabilität und Handhabung beeinträchtigen kann. Es weist alkalische Eigenschaften auf, mit einem pH-Wert, der typischerweise über 7 liegt, wenn es in Wasser gelöst ist. Diese Verbindung wird häufig in der Glas- und Keramikherstellung, als Flussmittel in der Metallurgie und als Reinigungsmittel aufgrund seiner Fähigkeit, Wasser zu enthärten, verwendet. Darüber hinaus hat es Anwendungen in der Landwirtschaft als Mikronährstoff für Pflanzen und in verschiedenen industriellen Prozessen. Sicherheitsüberlegungen umfassen das Vermeiden von Inhalation und Hautkontakt, da es reizend sein kann. Insgesamt ist Wasserfreies Borax eine vielseitige Chemikalie mit bedeutenden industriellen und haushaltsüblichen Anwendungen.
