Technical features: high temperature resistance, longer life span, applicable to the environmental temperature     ≤1100℃

Description: two types  1)95 alumina ceramic sheath ,

 the heating core is made from RE(rare earth), High temperature reached 1400 ℃ 

2)Using the silicon molybdenum ceramic, filling with ceramic powder and sintering them under the high temperature, tube diameter ≥Φ 10mm, what can also be used in hollow tube with double radiating surface process, this process can make the  elements long term working under the temperature ≤1400℃ with safety condition.
