摘要：

The standard Gibbs energies of formation of Mo(2)B, alpha MoB, Mo(2)B(5), and MoB(4) in the molybdenum-boron binary system were determined by measuring electromotive forces of galvanic cells using an Y(2)O(3)-stabilized ZrO(2) solid oxide electrolyte. The results are as follows: Delta(f)G degrees (Mo(2)B)/J mol(-1) = -193100 + 44.10T +/- 700(1198 K to 1323 K(925 degrees C to 1050 degrees C)) Delta(f)G degrees (alpha MoB)/J mol(-1) = -164000 + 26.45T +/- 700(1213 K to 1328 K(940 degrees C to 1055 degrees C)) Delta(f)G degrees (Mo(2)B(5))/J mol(-1) = -622500 + 117.0T +/- 3000(1205 K to 1294 K(932 degrees C to 1021 degrees C)) Delta(f)G degrees (MoB(4))/J mol(-1) = -387300 + 93.53T +/- 3000(959 K to 1153 K(686 degrees C to 880 degrees C)) where the standard pressure is 1 bar (100 kPa).
