Mo_4O_11 crystallizes in two different structures were depending upon the temperature of preparation, blow 890 K the monoclinic was obtained and above this temperature the orthorhombic was formed. The heats of reaction of these materials, MoO_2 and MoO_3 dissolved in strong base solution contained K_3[Fe(CN)_6] were measured directly by using of the conduction calorimeter. By using these direct measured data, the standard enthalpies of formation of orthorhombic and monoclinic Mo_4O_11 were determined indirectly by means of Hess's law of the summation. It was revealed that the A_fH^o of the orthorhombic Mo_4O_11 was lower than that of monoclinic one. The results will be reported in details., application/pdf}, pages = {97--99}, title = {低次モリブデン酸化物の熱力学的研究}, volume = {8}, year = {2015}, yomi = {スズキ, タカシ and エダ, カズオ} }
