Document Type and Number:
Japanese Patent JP6924433
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a particle for laminated molding that allows molding by laminated molding without making the addition of a binder an indispensable prerequisite, and can achieve high molding strength, and a molding for sintering using the same, and a method for producing an alumina sintered body.SOLUTION: Particles for laminated molding according to the present invention contain hydraulic alumina particles having 30-100 μm of D90, with the percentage of the particles of 0.1-10 μm in particle size being 20 pts.mass or more. A molding for sintering according to the present invention contains rehydrated alumina particles having 30-100 μm of D90, with the percentage of the particles of 0.1-10 μm in particle size being 20 pts.mass or more.SELECTED DRAWING: None
