Manganese borate is a colorless crystalline solid that is stable at room temperature. Its solubility is relatively low, soluble in dilute acid, slightly soluble in water and sodium hydroxide, slightly soluble in oil, and insoluble in alcohol. Manganese borate has good thermal stability and weak hygroscopicity. It will be decomposed if exposed to water for a long time. After absorbing moisture, the oxidation in the air accelerates, which has a drying effect on vegetable oil.
