检查了两种硼硅酸钠玻璃的微观结构。水蚀刻断裂表面复制品的电子显微照片表明，微相尺寸随着热处理温度和时间的增加而增加。可溶性和不溶性微相的相对量基本保持不变。完全浸出的玻璃的扫描电子显微照片显示，不溶相是随机互连的。显示了浸出玻璃孔中胶体沉积物的扫描电子显微照片，这些胶体沉积物是由热处理基础玻璃的酸浸出造成的。还包括显示各相溶解的电子显微照片。
Microstructures of two sodium borosilicate glasses were examined. Electron micrographs of replicas of water‐etched fracture surfaces show that the microphases increase in size with the temperature and time of heat treatment. The relative amounts of soluble and insoluble microphases remain essentially unchanged. Scanning electron micrographs of completely leached glasses show that the insoluble phase is randomly interconnected. Scanning electron micrographs of colloidal deposits in the pores of the leached glass, which result from acid leaching of the heat‐treated base glass, are shown. Electron micrographs showing re‐solution of the phases are also included.
