It is used for all kinds of friction materials with great success already. For lv disc brake pads especially the grade K0 (0 - 0.1 mm) is used. For higher coefficient of friction, such as cv brake pads and blocks or sintered brake materials, the coarser grade K1 (0 - 0.5 mm) is mainly used. Our customers report as follows: Stabilizes the coefficent of friction μ, Improves the thermo shock resistance, Swelling of the friction material is reduced, Improves performing in corrosive environment. These advantages are mainly caused by the interlocked crystallites (in the μm range) of the mullite. The hardness is 6 - 7 Mohs. The quantity in the formulation can vary between 2 - 8 %, depending on the requested coefficent of friction. The melting temperature is >1850°C. Due to the homogeneous phase constitution and a very low amount of impurities this quality offers considerable advantages compared with all other mullites. The constant high quality of our Sintered Mullites is based on careful selection and quality control of all raw materials. After pelletising or briquette forming, the raw materials are sintered close to the melting temperature. A highly homogeneous temperature distribution during the sintering process leads to constant high Mullite forming rates.
