specific gravity   2.5 2.8
manufacture rate % 23 5
flexural rigidity MPa at 25¡É 49 98
specific heat KJ/kg¡É at 25¡É ~1300¡É 1.0 1.0
heat conductivity W/m at 1000¡É 14~19 16~21
terminal resist §Ùcm AT 1000¡É 0.10 0.016
coefficient of thermal 1000¡É(x10~5/¡É) 4.5 4.5


Resistance temperature characteristic is negative resistance characteristic(where an increase in the temperature results in a decreased resistance) for the range of 650¡É~700¡É, but it will be positive resistance characteristic(where an increase in the temperature results in a increased resistance). However, the resistance is the measured value at the temperature of 1000¡É,which means it will different when you measure it in the general atmosphere. Therefore, Awareness is needed on the resistance value when you design a heater.




      D3 type (JIS standard R7501 2nd-class)
