Abstract:

Ni and Mg molybdates were prepared by an aqueous process and identified by x-ray analysis. Differential Thermal Analysis DTA of molybdates and their solid solutions mixed at various proportions were carried out. The spalling of NiMoO4 on cooling was observed. This large exothermic phase transformation was modified. Flexural strength of MgMoO4 bars were determined. Furnance designed to carry out this test at elevated temperature Vacuum Stability of bars made of NgMoO4 at high temperatures was observed. Slurry process of coating Molybdenum was carried out with some success and the same sintered at 950C in high vacuum. An attempt was made to study the coated material at high temperatures under high vacuum and desired controlled atmosphere by a metallograph. Author
