Abstract

The sintered process is an important link of ceramic, ultra high temperature materials in the production process. Therefore, studied the sintered ceramic process based on the thermal analysis and discussed the sintering properties of ceramic materials. At first, it introduced the sintered ceramic and thermoanalysis technology. Then, described the experimental materials and characterization methods of this experiment. At the end, it used the dilatometers to determine the sintering temperature range of the ceramic. It verifies dilatometers reli-ability to determine the sintering ceramic temperature range. Then, heat analysis study on sintering characteris-tics of ceramic materials, heating rate relation with optimum sintering temperature, and the ratio of particle size distribution effect on sintering performance. The main conclusion as following: 1) by using the dilatome-ters, the ceramics sintering temperature range is accurate and reliable. 2) The sintering process mainly physical and chemical changes of the ceramic body are: Room temperature 300 , excluding dry does not eliminate re-sidual moisture. At 300 - 1000 , the body weight loss significantly, no significant changes in volume. Kao-linite gradually transformed into metakaolin. At 1000 to sintering temperature, the body begins to shrink. With the increase of temperature, it caused severe contraction of the body densification. When the tempera-ture is higher than the sintering temperature, the body begins to swell. 3) The heating rate is higher; the best ceramic firing temperature is high.
