The influence of particle size of the load in the structure and morphology of the composite is an important factor in their final properties. This study will evaluate the behavior of the load of nickel ferrite calcined at different temperatures (700, 900 and 1200 ° C) with the polyamide matrix 6. In the preparation the polymer matrix was previously been dried in a vacuum oven at 80 ° C/48hs for eliminating humidity, and then the load was incorporated in the form of powders calcined at three temperatures in the mass concentration of 50%. Thereafter, the mixture was compressed to obtain composites, which were characterized by XRD and SEM. The results show XRD characteristic peaks of nickel ferrite and polyamide 6, showing that the calcination caused an increase in crystallinity of the load. SEM results show that the calcination caused an increase in the size of the agglomerates of the load, favoring significant changes in the morphology of the composite. |
