Friction properties of chambersite

To exploit the application of chambersite, original chambersite powders after mineral beneficiation were ball-milled into powders with the average particle size less than 10μm by using a high energy ball mill. The milled powders were processed into disk-shaped samples by spark plasma sintering (SPS). X-ray diffraction (XRD) and scanning electron microscopy (SEM) were utilized to characterize the structure, shape and size of the samples, and a controlled atmosphere micro friction tester was used to investigate the friction properties of the samples. It is shown that the samples belong to orthorhombic Mn₃B₇O₁₃Cl, the friction coefficient is from 0.2 to 0.6, and the wear loss is about 1×10^-9 cm³·N^-1·m^-1, which let chambersite have a good prospect of application in the field of friction materials packing.
