Halloysitum Album is one of the most commonly used mineral drugs. It is often found fake or mixed in the market, which is related to the unclear identification of mineralogy. The purpose of this paper is to observe the characters and identify them by mineralogy. The mineralogical and spectral characteristics of Halloysitum Albumfrom different places on the market were compared using scanning electron microscopy (SEM), X-ray diffraction (XRD), semi-quantitative trace element spectroscopy, differential thermal analysisand infrared spectroscopy(IR). The results are as follows: (1) Halloysitum Album is white, with earthy luster, small hardness, water-absorbing and sticky tongue, and slightly earthy and fishy. The main minerals are kaolinite, illite and quartz. The main impurity minerals are feldspar, calcite and limonite. (2) The SEM results showed that all white stone lipids had grid-like fiber structure, and the main components were O, Si and Al. (3) The results of XRD showed that the main diffraction lines of the samples are 7.44(3), 3.53(4), the main composition is kaolinite, the diffraction lines are 10.45(5), 4.51(3) and illite, and the quartz diffraction lines are 5.04(3), 4.51(3), 3.06(10), secondary diffraction lines show the presence of and small amounts of feldspar, calcite and limonite. (4) The micronutrient spectrum Quantitative analysis showed that Ca, Mg, K, Na and Cr were the main components in the white stone lipids. (5) The differential thermal analysis (DTA) showed an obvious heat absorption effect of kaolinite and illite. (6) The results ofIR showed that the high frequency bands of 3 700～3 000 cm-1 have sharp and strong absorption peaks near 3 440.98, 3 621.18 and 3 620.45 cm-1, respectively. All the samples can be divided into 1 200～1 000, 950～900 and 800～600 cm-1 bands. The bands of the three samples are the same, and the main mineral composition is kaolinite. To sum up, the quality of commercially available Halloysitum Album can be judged effectively using properties, mineralogy, SEM, IR, XRD and differential thermal analysis.
