Production of magnesium oxide polyhydrates as fillers for electrorheological suspensions

Abstract

The influence of the production conditions of magnesium hydroxide on its composition, in particular the content of the non-structural “superstochiometric” water, which can be localized in the interlayer space of the layered structure. The conditions of generation and formation of the magnesium hydroxide crystal structure of brucite (nemalite) type, containing up to 8 wt % “superstochiometric” water, which is removed by heating up to 300–350?C. Observed the formation of basic magnesium carbonate using distilled water containing dissolved carbon dioxide. When used distilled water containing dissolved carbon dioxide, magnesium basic carbonates are formed.
