THE EXPERIMENTAL RESEARCH ON SINTERING TEMPERATURE TO Fe_2O_3 POWDER SINTERING DENSITY

针对烧结温度等参数对Fe2O3粉末压制烧结密度的影响进行了试验。结果表明：在实验条件相同情况下，粉末粗细颗粒比在85％时压坯密度最高；随着压制压力的升高，在400MPa以下压坯密度上升速率较大，在400～650MPa之间压坯密度呈平台型和上升型交替趋势；烧结块在最终烧结温度为1240℃烧结获得的密度最高。

Aim at finding the influence of the parameter such as sintering temperature on sintering density of the Fe2O3 powder during suppressing, we conduct an experiment. The result shows that： under the same experimental condition, the sintering density is the highest when the coarse and fine Particle ratio of powder is at 85%. Along with suppressed pressure ascension, the ascend speed is faster below the 400MPa, and sintering density gets a plateau -rising type alternate tendency between 400MPa -600MPa. The sintering part obtains the highest density when the final sintering temperature reaches 1240℃.
