The quaternary system KCl-MgC12-Mg(OH)2-H2O and the associated systems, (a) KCI-Mg(OH)2-H2O and (b) MgC12-Mg(OH)2-H20 were investigated at 100° Though the isotherm (a) exhibited nothing new, isotherm (b) exhibited a new basic magnesium chloride, MgC12•2Mg(OH)2•6H2O, as a solid phase in such a solution having a higher concentration of magnesium chloride than 51.5 gram per 100 gram water. The solid phases of quaternary isotherm were the new basic magnesium chloride, bischofite, carnallite, potassium chloride and magnesium hydroxide.
