摘要: 本文報導了一種人工合成及鑒定純錳薔薇輝石的方法。合成的錳薔薇輝石在室溫時可被稀酸分解約20%。在非常溫下(約100℃)可被稀鹽酸分解57%以上。用量熱計測得室溫時錳薔薇輝石與稀鹽酸反應的反應熱是-85.1±3.6kJ·mol-1。Abstract: In this paper, the method of synthesis and charaterization of pure rhodonite are discussed.At room temperature about 20% by dilute acid, and at about 100℃ more than 50% by dilute hydrochloric acid can be decomposed. It is found by calorimetry that reaction of rhodonite with hydrochloric acid releases the heat to be 85.1±3.6kJ/mol.
