It was believed that either alumina reacted with impurities in the iron powder or the surface diffusion caved the alumina particles to stick to the iron powder surfaces. Another approach was to use the air classifier mill to break up the sintered iron cakes into powders. The morphology of such particles was classified into 4 types in this study: irregular, equalaxed, near spherical, and flaky. The morphological differences were affected by the extent of sintering. The higher the extent of sintering, the stronger the inter-particle bonding.

此外，本实验利用空气分级气流粉碎机将还原后的烧结体进行粉碎，实验结果显示粉碎后的粉末形貌可以分为四种，不规则形、等轴形、近球形和片形，形貌上的差异是由於还原时铁粉烧结程度的不同，烧结程度越高，粉末间键结强度越强，因此粉碎过程中会产生高程度的塑性变形，以至於粉末形貌越来越接近球形，最后因粉末表面大量加工硬化产生破裂，形成片状碎屑。

China has still a large number of residential construction using sintered clay brick.

中国仍然有大量的住宅建筑使用烧结粘土砖。
