The heavy magnesium carbonate is also known as basic magnesium carbonate. It is widely applied in the flour improver. It improves the dispersibility and mobility of flour improver, and shows a favorable development foreground. Adopting felicity conditions, the heavy magnesium carbonate is white powder. This article has mainly studied the influence from reaction period of raw materials concentration to crystals.
The crystal of heavy magnesium oxide has maximum bulk density. The grain nucleation and grain growth is one of the key factors to decide the crystal particle size. When the saturability of magnesium carbonate is large and the raw materials concentration is less, the carbon dioxide has a large emitting rate. At the same time, it causes the raw materials concentration of loose deposits is too high or too low. The response time is the influence to heavy magnesium carbonate’s bulk density from the temperature. The crystal of heavy magnesium carbonate has the largest bulk density, and this magnesium carbonate is easy to lead hypersaturated state.
