The invention belongs to the technical field of brucite detection, and particularly relates to a method for detecting the content of magnesium hydroxide in brucite. The method for detecting the content of magnesium hydroxide in brucite provided by the invention comprises the following steps: performing thermogravimetric analysis on brucite to be detected to obtain a thermogravimetric curve, and obtaining the water weight loss ratio of the brucite to be detected according to the thermogravimetric curve; the mass content of magnesium hydroxide in brucite is calculated through the formula I; the thermogravimetric curve temperature interval of the moisture weight loss ratio is 300-650 DEG C. The determination method provided by the invention is simple to operate and strong in operability, the whole determination process takes about 1 hour, and compared with a national standard determination method, the detection efficiency is improved, and data can be provided for daily production detection in time. 本发明属于水镁石检测技术领
