Abstract

A new method for producing highly dispersed strontium aluminate with specified properties (low bulk density, particle size and shape) is described. The essence of the method is the sequential multi-stage heat treatment of a concentrated water-carbohydrate solution of Al(NO₃)₃, Sr(NO₃)₂, and D-glucose. The final product has a molar ratio of SrO : Al₂O₃ = 1 : 1. The main stages of the synthesis have been characterized by X-ray powder diffraction, SEM, and TEM methods. The initial stages of crystallization of SrAl₂O₄ upon heating at 1400°C have been revealed.

高分散铝酸锶的低温合成

摘要

描述了一种生产具有特定性能（低堆积密度、颗粒尺寸和形状）的高度分散的铝酸锶的新方法。_{该方法的本质是对Al(NO 3} ) ₃、Sr(NO ₃ ) ₂和D-葡萄糖的浓缩水-碳水化合物溶液进行顺序多级热处理。最终产物的摩尔比为SrO : Al ₂ O ₃ = 1 : 1。通过X射线粉末衍射、SEM和TEM方法对合成的主要阶段进行了表征。已经揭示了在 1400°C 加热时SrAl ₂ O ₄结晶的初始阶段。
