摘要
通过脱水处理制度的研究,确定了合适的升温速度范围和明显发生与不发生封孔致密化的边界温度。利用电子衍射技术,研究了α—FeOOH的微晶和颗村之间的取向关系,并对孔洞成行排列进行了解释。
By study of the dehydration treatment system, this paper determines a suita. ble range of temperature rising rate and the boundary temperature Which results in seal. ing densification efficiently. Direction relation between α—FeOOH microcrystal and particles is researched by TEM diffiraction technique and the formation of pores in a raw is explanated.
