| titleOfInvention | Translucency gradual change Coloured Anodizing zirconia material and its preparation technology |
| abstract | The present invention relates to a kind of translucency gradual change Coloured Anodizing zirconia material and its preparation technology, belong to ceramic material for dental applications technical field.Described translucency gradual change Coloured Anodizing zirconia material, including the bottom from bottom to top set gradually, intermediate layer A, intermediate layer B, intermediate layer C and upper strata five-layer structure, it is prepared from respectively by 3Y TZP, (3.5~4.5) Y PSZ and tri- kinds of powders of (4.5~6) Y PSZ from colouring agent by different quality proportionings；Described preparation technology is that the powder layering of recipe ratio is placed in die cavity, base substrate is obtained after dry-pressing formed, cold isostatic compaction, then base substrate is placed in sintering furnace and carries out pre-sintering, after resected, double sintering, obtain translucency gradual change Coloured Anodizing zirconia material.The zirconia material of the present invention disclosure satisfy that requirement of the tooth cut end to translucency, while the regularity of distribution of natural teeth color can be simulated, its preparation technology is simple, easy to operate. |
