1. Rupture strength for base body:

440Kg/cm2

2.Resistance in common temperature:

10¹² ohm ⁰cm

3.Property:good chemical stability;strong causticity-resistance;perfect oxidation-resistance

4.Heat losing in the non-radiation surface is small

5.The base body is heated to 800 C and put in cold water repeatly for ten times and no cracking.

6.The radiated element is heated after electrifying to rating power and immerged into cold water after interruption of power supply for forty times without damage.

7.The max radiance of element>0.9

8.The effect of energy saving is obvious,increasing 10-25% compared with silicon carbide element

9.The life span can prolong more than a few times compared with silicon carbide e
