Preparation, properties and phase transition of mesoporous hydromagnesite with various morphologies from natural magnesite

Hydromagnesite with different morphologies has been synthesized using magnesite as raw materials. The influences of pyrolysis temperature, the pH value of the magnesium bicarbonate solution and pyrolysis time on the preparation process of hydromagnesite were investigated. The synthesized samples wer...
