摘要：

Contact angles (theta(wicking)) with apolar and polar liquids on monosized synthetic cuboid hematite particles were obtained by thin layer wicking. Contact angles (theta(adv)) of these liquids on films of hematite particles were also measured by the advancing drop method. The values of theta(wicking) and theta(adv) coincided within a few degrees. Thus, the thin layer wicking method and the direct contact angle approach appear equally valid.
