摘要：
The use of kaolin in any industrial segment requires previous physical and chemical treatment to minimize the amounts of impurities to or below standard levels established according to the desired application. Wastes from kaolin processing from the Amazon region were characterized by DTA-TGA and XRD. This paper shows the thermal transformations of the rejects studied at temperatures of 600 degrees C, 700 degrees C, 800 degrees C, 900 degrees C, 1000 degrees C, 1300 degrees C, 1400 degrees C and 1500 degrees C, tests with pyrometric cones and ceramic properties of the sintered materials aiming their use in refractory materials.
