 SINTERING TEMPERATURE 1450°C -  1500°C  - 1550°C

 Sintering cycles are based on the experience of CO.N.CE.P.T. and on technical data stated by manufacturers of raw materials

Sintering temperature is 1450°C. In order to enhance translucency is possible to increase temperature to 1500°C or 1550°C, provided that different hold time is followed (as showed in detailed table). Exceeding the recommended sintering temperature could lead to deterioration of chemical and mechanical characteristics of the product.

It's possible to achieve a excellent tranlucency decreasing the overall time of the sintering cycle:

  • 1450 °C = hold time 3,5 hours
  • 1500 °C = hold time 90 minutes or 2 hours (see table)
  • 1550 °C = hold time 30 or 90 minutes (see table)

 

Sintering is a very delicate phase which influences final characteristics of the structure. In order to avoid distortions or cracks and to achieve the best aesthetic result consult the section SINTERING.


In case of use of sintering kilns that are not programmed to insert all the detailed steps,it is possible to make sintering cycles with less steps but with slower heating rate and/or cooling rate. See example below.

1.            950°C - 1330°C     =4°C/min=240°C/h

2.            1330°C                  =hold time 15 minutes

3.            1330°C - 1450°C    =7°C/min=420°C/h.            

4.            1450°C                  =hold time 3,5 hours

The cycle could be simplified like this:

1.            950°C - 1450°C     =4°C/h

2.            1450°C                  =hold time 3,5 hours
