Zotion Zirconia Sintering Instruction
May 08, 2019| 
For the lastest Zotion zirconia disc(upgraded) after February 2019, we advise follow the new sintering chart. After thousand times of testing by our own lab, our technical department advises that our new zirconia discs can be fast sintered in the following way which is more flexible according to clients different requests.
Step | Start Temperature(℃） | End Temperature(℃) | Time(min) | Speed(℃/Min) |
1 | 50 | -2.0 | 0 | From step 2 |
2 | 50 | 300 | 40 | 7.5 |
3 | 300 | 800 | 100 | 5 |
4 | 800 | 1300 | 200 | 2.5 |
5 | 1300 | 1530 | 46 | 5 |
6 | 1530 | 1530 | 120 | holding |
7 | 1530 | Room temperature | Natural cool | |
Old Sintering Chart for Zotion Zirconia disc
A.The speed of rising speed can decide according to different clients’ request.
B. If high temperature rising speed, hold 1450℃ longer relatively, if lower temperature rising speed, can hold 1450℃ shorter relatively.
C. the key point of this new sintering chart is the highest temperature 1450℃.
step | Start Temperature(℃) | End Temperature(℃） | Time(min) | Speed(℃/min) |
1 | 0 | 1450 | 97-290 | 5-15 |
2 | 1450 | 1450 | 120-150 | holding |
3 | 1450 | Room temperature | Natural cool | |
