%X KA1(OH)2CO3 powder was prepared by a hydrothermal method using A1(OH)3 and KHCO3 as the starting material. The influence of the composition of the starting material, reaction temperature, acidity of the reaction medium and reaction time on the formation, morphology and particle size of KA1(OH)2CO3 powder was systematically investigated. The research results show that fibrous particles will be obtained at most conditions. The length and diameter of particles increase with the ratio of A1(OH)3 to KHCO3 or the reaction temperature increasing. The morphology and particle size of the products are significantly affected by the acidity of the reaction system, and pH=9.5 is optimal for the preparation of the KA1(OH)2CO3 powder with minimal diameter and the best uniformity.
