The cation deficient complex oxides of (Ca/Sr)MoO4 - BiVO4 - Bi2Mo3O12 triple system are promising photocatalysts and pigments. Compounds with general formula of Ca1−1.5x-yBix+yФxMo1-yVyO4  and Sr1−1.5x-yBix+yФxMo1-yVyO4 were synthesized byconvention solid state technique in the range of 550–720 °C. Two wide regions of the solid solutions (ordinary and superstructured scheelite-type phases respectively) were found for each system. The diffuse scatering of homogeneous samples was investigated in the range of 190–1100 nm. Energy gaps calculated with linear approximation of Kubelka-Munk function decreases with bismuth and vanadium content.

This paper presents the development and qualification of high temperature electronic module packaging technology to service the requirements for extended and reliable operation at 225°C (437°F) for applications in the Oil & Gas, Automotive and Aerospace markets. It also covers the application of this technology to the first in a range of DC-DC converter modules and is based on Cissoid's ‘ETNA’ semiconductor components.
