Document Type and Number:
Japanese Patent JP5841753
Kind Code:
B2
Abstract:
Slurry (7) based on radically polymerizable binder, polymerization initiator and filler, comprises (in wt.%, based on the total mass of the slurry): (a1) at least one acidic monomer (I) (1-30); (a2) at least one non-acidic radically polymerizable monomer (0-50); (b) photoinitiator (0.001-2); and (c) ceramic- and/or glass ceramic particles (30-90). Slurry (7) based on radically polymerizable binder, polymerization initiator and filler, comprises (in wt.%, based on the total mass of the slurry): (a1) at least one acidic monomer of formula (H1G-Y1-) a-X-(Z-P1G) b) (I) (1-30); (a2) at least one non-acidic radically polymerizable monomer (0-50); (b) photoinitiator (0.001-2); and (c) ceramic- and/or glass ceramic particles (30-90). X : (a+b)-valent linear at least 2C aliphatic (optionally substituted), branched at least 3C aliphatic, 6-20C cycloaliphatic, 6-20C bicyclic group, 6-20C tricyclic group and/or 6-20C aromatic group (all optionally comprise at least one ether group), where X is optionally present; P1G : radically polymerizable group; H1G : -COOH-, -PO(OH) 2, -O-PO(OH) 2or -SO 3H; Y1 : divalent linear 2-40C aliphatic, branched 3-40C aliphatic, 5-40C cycloaliphatic or 5-40C aromatic group (all optionally comprise at least one ether-, thioether-, amide- and/or ester group), where Y1 is optionally present; Z : divalent linear 2-40C aliphatic or branched 3-40C aliphatic (both optionally comprise at least one ether-, thioether-, amide- and/or ester group), where Z is optionally present; a : 1-5; and b : 1 or 2. An independent claim is also included for producing a ceramic- or glass ceramic molded part, comprising (i) producing a green compact, in which the above slurry is hardened by locally introducing radiation energy with the formation of geometrical mold of the green compact, (ii) subjecting the green compact to heat treatment for removing the binder (debinding) to obtain a white compact, and (iii) sintering the white compact.
