摘　　要：Series of Gd2O3/X-NBR composites were prepared by in-situ reaction at different temperatures (100 and 160℃) and different processing time. The influence of processing time and processing temperature on dispersion of Gd2O3 was investigated, and the relationship between magnetic property and temperature was also discussed. The results show that, the mass magnetizability (xg) descends as temperature rising. Processing temperature and time do not exhibit evidenced effects on the mass magnetizability (xg). All the composites show to be antiferromagnetic.Series of Gd2O3/X-NBR composites were prepared by in-situ reaction at different temperatures (100 and 160℃) and different processing time.
