本文提出了一种新的表征方法，它可以揭示光学各向异性颗粒--氧化铝中存在着浓度极低、取向极低的大颗粒晶体。它包括足够的浸泡液体，使颗粒透明，并随后进行偏振光学显微镜检查。这种方法很容易检测到大的氧化铝颗粒：在交叉偏振光模式下，它们是清晰可见的。颗粒在基质颗粒中的取向也很明显：颗粒上出现了黑色的十字图案，表明颗粒沿颗粒的切线方向取向。讨论了这些特征对陶瓷加工的意义。
This paper presents a novel characterization method which can reveal the presence of large crystalline particles of very low concentration and particle orientation in optically anisotropic granules, i.e. alumina. It involves an adequate immersion liquid which makes granules transparent and subsequent polarized optical microscopic examination. Large alumina particles are easily detected by this method: They are clearly visible under the crossed polarized light mode. Particle orientation in the matrix particles was also noted: Dark cross pattern appeared on the granules, showing the orientation of particle along the tangential direction of granules. The significance of these features for ceramic processing was discussed.
