['To determine the sintering temperature range and the best temperature of coloration of HN-97 porcelain stain,and matched porcelain powders.', '(1) The authors used prepared experiments of sintering temperatures and different sintering temperatures with different porcelain powders.', '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.'] Do [ Study of sintering temperature of HN-97 porcelain stain ]?
