AbstractThe phase equilibrium of 2MgO.2B(2)O(3).MgCl2.14H(2)O-H3BO3-H2O system at 30degreesC has been studied. The experimental results indicate that the phase transformation product is inderite (2MgO.3B(2)O(3).15H(2)O) when the mass fraction of H3BO3 is in the range from 0% to 2.50%, kurnakovite (2MgO.3B(2)O(3).15H(2)O) from 2.50% to 5.00%, hungtsaite (MgO.2B(2)O(3).9H(2)O) from 5.00% to 5.60%, successively. When the mass fraction of 1431303 is higher than 5.60%, the macallisterite (MgO.3B(2)O(3).7.5H(2)O) crystallizes from the solution. The mechanisms of dissolution and phase transformation have been proposed.
