| description | PROBLEM TO BE SOLVED: To provide a magnetite particle from which a brake friction material having high frictional resistance can be obtained.SOLUTION: A magnetite particle of the present invention has a particle diameter D of primary particle measured by electron microscopic observation, of 0.8 μm or more and 10 μm or less. The magnetite particle is for use by blending into a brake friction material. It is suitable for the primary particle to have a polyhedral shape. It is also suitable to include binding particles in which a plurality of the primary particles are bound.SELECTED DRAWING: Figure 1
【課題】摩擦抵抗が高いブレーキ用摩擦材を得ることができるマグネタイト粒子を提供すること。【解決手段】本発明のマグネタイト粒子は、電子顕微鏡観察によって測定された一次粒子の粒径Ｄが０．８μｍ以上１０μｍ以下である。このマグネタイト粒子はブレーキ用摩擦材に配合されて用いられる。前記一次粒子は多面体の形状を有することが好適である。複数の前記一次粒子が結着した状態になっている結着粒子を含むことも好適である。【選択図】図１ |
