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.
