锰方硼石的摩擦性能

为了开拓锰方硼石的应用，将选矿之后粉末状锰方硼石进行高能球磨处理，得到尺寸小于10μm的粉末颗粒，采用放电等离子烧结，将得到的粉末颗粒制备成圆片状样品.使用X射线衍射仪和扫描电子显微镜对粉末状锰方硼石和摩擦片样品进行表征，证实该样品为斜方晶系的Mn₃B₇O₁₃Cl.用WTM-ZE可控气氛微型摩擦试验仪测试锰方硼石样品的摩擦性能，其摩擦因数范围为0.2~0.6，磨损量小，为1×10-9 cm3·N-1·m-1左右，表明锰方硼石在摩擦材料填料领域有应用前景. 

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.
