本文研究了纯氧化铝和二氧化硅混合物在高温下的平衡关系。结果用平衡图的形式简明地表示出来，并讨论了它们对陶瓷问题的影响。
该图的主要特征是没有化合物Al_2O_3·SiO_2，唯一的化合物是3Al_2O_3·2SiO_2。后一种化合物的晶体存在于所有氧化铝-硅质耐火材料中。测定了这些晶体的光学性质，并与硅线石Al_2O_3·SiO_2的光学性质进行了比较，硅线石被认为是一般存在于耐火材料和粘土体中的结晶化合物。
讨论了天然硅线石的加热行为。
This paper deals with a study of the equilibrium relations of mixtures of pure alumina and silica at high temperatures. The results are expressed concisely in the form of an equilibrium, diagram and their bearing on ceramic problems is discussed.
The principal feature of the diagram is the absence of the compound Al2O3.SiO2, the only compound being 3Al2O3.2SiO2. Crystals of this latter compound occur in all alumina-silica refractories. The optical properties of these crystals have been determined and are compared with those of sillimanite, Al2O3.SiO2, which has hitherto been regarded as the crystalline compound occurring in refractories and clay bodies in general.
The behavior of natural sillimanite on heating is discussed.
