水热法合成羟基氧化镓与优化探索

Abstract

Abstract: Gallium oxide hydroxide（GaOOH） is an important raw material for synthesizing GaN and its micro morphology has a great effect on the physical properties of the GaN products. Gallium oxide hydroxide could be synthesized by hydrothermal method with gallium oxide，concentrated hydrochloric acid，and ammonia solution as raw materials.Effect of concentrated hydrochloric acid dosage on the purity of GaN was discussed.The as-prepared products were characterized by XRD，and results indicated that the products were gallium oxide hydroxide，and the more concentrated hydrochloric acid added，the purer gallium oxide hydroxide was obtained.

Key words: gallium oxide hydroxide；hydrothermal synthesis, GaN

CLC Number:

TQ133.51
