Title:
耐熱性材料の補強のためのセラミック繊維
Document Type and Number:
Japanese Patent JP4630394
Kind Code:
B2
Abstract:
The ceramic fibers for reinforcement of refractory materials comprise sintered bauxite and have a length/diameter ratio above 10. The fibres are cylindrical or prismatic in form and are truncated on two surfaces, in particular the surfaces parallel and perpendicular to the axis of the cylinder or prism. Preferably, the cross-section of the fibers is in the form of a star. Independent claims are given for: (a) a refractory concrete based on metal oxides and reinforced by the addition of 0.1-50 wt. % of the above ceramic fibers; and (b) use of the refractory concrete for components intended for casting of silicon or its alloys.
