High temperature resistant ferric yellow
Alkaline oxides with relatively stable chemical properties, bright and pure color, with good pigment characteristics, such as tinting strength and high hiding power. Light resistance of 7~8 grade. Insoluble in alkali, slightly soluble in acid, can be completely dissolved in concentrated hydrochloric acid. Poor thermal stability, heating to 150~200 DEG C began to dehydration, when the temperature rose to 270~300 DEG C dehydration quickly and become iron red Fe2O3.
