本文对赭石在不同煅红温度下的煅淬品进行了化学成分比较分析,通过实验初步找到其煅红温度与氧化亚铁含量的关系。结果证明,赭石煅红温度只有严格控制在650℃,其氧化亚铁含量最高,并易于粉碎,保证炮制品的质量,有益于提高临床疗效。 In this paper, the chemical compositions of vermiculite calcined at different calcined red temperatures were compared and analyzed, and the relationship between calcined red temperature and ferrous oxide content was initially found through experiments. The results show that the temperature of vermiculite calcined red is only strictly controlled at 650°C, and its ferrous oxide content is the highest, and it is easily crushed to ensure the quality of processed products, which is beneficial to improving clinical efficacy.
