Anwendungen & Verwendung
Verwenden
Lithium metasilicate is an inorganic compound that has a high resistance to heat and acid. It is used as an additive to zirconium oxide membranes, which are used in membrane separation processes. It has been shown to have a high transport capacity for water vapor and sodium carbonate. This property makes it suitable for use in the clinical setting where it has been shown to have biological properties and clinical relevance.
Verwenden
To calibrate thermoelements.
