Liner thermal expansion coefficient of NAC Ceramics from Low temperature(Under 0℃)～Room Temperature～High temperature
- The table below shows the linear thermal expansion coefficient (CTE) of NAC’s ceramics in the temperature range of -50 ℃ to 350 ℃, and the graph of linear thermal expansion coefficient vs. temperature. The data shown are representative values and not guaranteed values.
- After decreasing the temperature from room temperature to -60 ° C at 5 ° C / min, the dimensional change was measured at a heating rate of 10 ° C / min. The measurement was conducted at a governmental public organization in the Kanto area.
