Hydroboracite

ID: hydroboracite

CaMgB6O8(OH)6·3(H2O)

Description

Hydroboracite is a hydrated calcium-magnesium borate mineral defined by the chemical formula CaMgB6O8(OH)6·3H2O. First identified in 1834 at Kazakhstan’s Inder Lake, it functions as a secondary source of boron within geological deposits. In the context of ceramic science, minerals within this borate classification are primarily valued for their fluxing properties, as boron serves to lower the melting temperature of glass-forming mixtures and enhance the flow characteristics of glazes. While it is characterized as a minor ore, its presence provides a specific mineralogical pathway for incorporating essential boron into vitrified ceramic bodies and glass structures.
