Thermal decomposition of potassium titanium oxalate [PDF]
Journal of the Serbian Chemical Society, 2011 The thermal decomposition of potassium titanium oxalate (PTO) was studied using non-isothermal thermogravimetry at different heating rates under a nitrogen atmosphere. The thermal decomposition of PTO proceeds mainly through five stages forming potassium
