Synthesis and Thermodynamic Properties of Magnesium Borates

Abstract

It is well known that the magnesium borates are important materials in all fields. In this paper, the process on synthesis and thermodynamic properties of several hydrated magnesium borates including MgO·2B2O3·9H2O (hungchaoite), MgO·3B2O3·7.5H2O (mcallisterite), MgO·3B2O3·7H2O, 2MgO·3B2O3·17H2O, MgO·3B2O3·5H2O (aksaite) were summarized. The key problems existed and the new trends in the future were also carried out.
