[Study of sintering temperature of HN-97 porcelain stain].
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.


CONCLUSIONS
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.
