摘　　要：为使二步过碱法由卤水生产的镁砂中硼含量下降，本文提出以经树脂脱硼后的卤水作为第二步中的调制液。实验证明，用此法所得镁砂中硼的含量可比二步法低６３％。For lowering the B_2O_3 and CaO content in magnesia from brine by two-step-overlimed method,a modification was proposed,i.e.,the brine deboronized by resin instead of raw-brine is used in the secend step.By this modification the B_2O_3 content in magnesia is 63% lower than that by conventional two-step method.
