Mainly used in dental Zirconia sintering , and also used in other material Sintering and annealing

Proper Temperature

It should be noted that recent studies indicate that firing at approximately 1500⁰C - 1550⁰C (depending on the temperature accuracy of the furnace) produces maximum strength in zirconia and that firing above and below the recommended temperature by just 150⁰C can result in lower strengths due to grain growth. A specific case in the study showed that strength drops from about 1280 MPa at 1500⁰C to about 980 MPa at 1600⁰C and only about 600 MPa at 1700⁰C.

In addition, a higher temperature may result in lowered stability and uncontrolled transformation, causing cracking of the zirconia. And that’s just the physical property changes. Temperatures that are too high for the material also cause a lowering of translucency. Higher is not always better! Sticking to the manufacturer’s recommended firing schedule is critical, as long as the manufacturer is reputable. Most yttria partially-stabilized zirconia materials attain their ideal physical, mechanical and esthetic properties at approximately 1550⁰C.

Sintering

Every batch of zirconia block has gone though a completely sintering test. The sintering methods have a great impact on blocks’ properties, such as translucency, dyeing results, strength, hardness and ageing resistance, which will affect the blocks’ final stability. Therefore, please follow the sintering curve of it.
The translucency of restorations is closely related to sintering temperature and regular maintenance of sintering furnace. Please follow the below temperature chart.
