title: Protodolomite Synthesis at 100{degrees}C and Atmospheric Pressure.
abstract: Ordered protodolomite, CaMg(CO(3))(2), has been synthesized at 100 degrees C by reaction of metastable precipitated carbonates with aqueous magnesium-bearing solutions. Initial reaction products have expanded crystallographic cells, attributed to the presence of structural water. Longer reaction time produces a protodolomite approaching ideal composition and exhibiting order reflections in x-ray powder.
