[Study of sintering temperature of HN-97 porcelain stain]
1No.411 Hospital of PLA, Naval Stomtological Research Center, Shanghai 200081, China.
Objective:
To determine the sintering temperature range and the best temperature of coloration of HN-97 porcelain stain,and matched porcelain powders.
Methods:
(1) The authors used prepared experiments of sintering temperatures and different sintering temperatures with different porcelain powders.
Results:
The results showed sintering temperature range of the stain was 820-955 degrees centigrade; (2)The stain can be matched with many porcelain powders (e.g.Vita,Densply. Shofu and Shanghai); (3)Surface of stain was smooth, colour was stable,integrate was good.
Conclusion:
The stain can be used once coloration and glaze for restoration of porcelain, autoglazing temperature of which is between 820-955 degrees centigrade and the operation is easy.
