| 发明名称 | Method for preparing boron fertilizer | ||
| 摘要 | A method for preparing a boron fertilizer, including: (1) heating boric acid to a temperature of 180-200° C., maintaining the temperature for 20-30 min for dehydration of the boric acid to yield pyroboric acid; and (2) cooling down the pyroboric acid to a temperature of 40-60° C., crushing, and screening to yield a powdered, weakly acidic, high-content boron fertilizer. The method is energy-saving, environmentally friendly, and low in cost. The resulting boron fertilizer is weakly acidic, fast in dissolution rate, and has excellent in compounding performance | ||

| 主权项 | 1. A method for preparing a boron fertilizer, the method comprising the following steps: a) heating boric acid to a temperature of less than 200° C. and not less than 180° C., maintaining the temperature for 20-30 min for dehydration of the boric acid to yield pyroboric acid; and b) cooling down the pyroboric acid to a temperature of 40-60° C., crushing, and screening to yield the boron fertilizer, wherein the boron fertilizer has a pure boron content of between 22.5% and 23.5%. | ||
