  • Kibushi clay is included in this range, the surface lubricity (smoothness) becomes good.
  • Mica is added to improve the followability of the disk material shaft to thermal expansion. Since the shaft into which the disk material is inserted is made of metal, when exposed to a high temperature, the shaft expands thermally and extends along the axial direction. At this time, since the disk material has a lower coefficient of thermal expansion than metal, the disk material cannot follow the elongation of the shaft, and the disk materials are separated from each other. On the other hand, mica has a very thin layer structure, and when heated, it undergoes a crystal transformation, but at that time, it tends to expand in the layer direction, and this expansion in the layer direction leads to thermal expansion of the shaft of the disk material. The follow-up performance increases.

If mica is less than 20% by weight, the ability to follow the thermal expansion of the shaft will be low, and if it exceeds 40% by weight, it will be difficult to disperse uniformly in the slurry, and there is a concern that variations in physical properties of the disk base material will increase.

  • the base material can be manufactured by forming an aqueous slurry containing inorganic fibers, kaolinite and mica into a plate shape and drying it. At this time, it is efficient and preferable to use a papermaking method. That is, an aqueous slurry containing a predetermined amount of inorganic fiber, kaolinite and mica, if necessary, a coagulant aid, organic fiber, organic binder, etc. is prepared, and this aqueous slurry is formed into a plate shape by a paper machine and dried.
