Thermal analysis of several compositions in AI2O3-H3PO4, AI2O3-H3PO4-CrO3, AI(OH)3-H3PO4and AI(OH)3-CrO3-H3PO4systems was carried out for the purpose of ascertaining the trend of the reactions on heat treatment. CrO3in aluminium phosphate bonds reduces moisture sensitiveness of the product. CrO3was incorporated wth H3PO4to the extent up to 30. The different experiments were carried out up to 1000°C. Thermogravimetric curves indicated that the course of dehydration of AI2O3-H3PO4was prolonged in the presence of CrO3. An interesting feature of the DTA curves of AI(OH)3-H3PO4and AI(OH)3-H3PO4-CrO3was the absence of the endothermic peak at 120°C in the presence of CrO3. The various peaks and rate loss for the above systems were discussed and probable mechanisms suggested. © 1982 Taylor & Francis Group, LLC.
