Thermal Decomposition of Alkaline Earth Chromates, Oxalates and Chromate-Oxalate Mixtures. The Ba, Sr, and Mg Compounds
Cr(V) and Cr(III), dispersed at the surface of various oxidic materials, play an important role as catalytic species. The present contribution reports a detailed investigation, using a combination of various physical techniques (thermogravimetric analysis, mass spectrometry, e.p.r., ir-spectroscopy, and X-ray diffraction),of some methods of preparing and stabilizing such dispersed ions.
