SiC heating elements
SiC heater elements Introduction

Protech SiC (Silicon carbide) heating elements is produced by using the material of high purity silicon 

carbide and adopting German unique high temperature sintering technology. Now Protech SiC heating 

elements have become the first choice of lots of customers. 

SiC heater elements outstanding features  

1. High heat surface temperature: up to 1500C 

2. Large infrared radiation rate: 5 ~10 times the output of Nichrome wires

3. High mechanical strength, bending resistance reaches to 100~120MPa

4. Perfect thermal shock capability 

5. Small deformation in high temperature

6. Special technology to spread a protection film on the surface of hot zone, which enchance the 

antioxidant property evidently and lengthen the service life.  

7. Easy to install and maintenance 

6.  Free from noise and air pollution 

7.  Many shapes for your option, such as, GC, GD, GDD, SD, SG, U type, W type, etc. 

SiC heating elements Application

With SiC heating elements equipped with automated power supply system, not only can high accurate 

stable temperature be gained, but temperature can be adjusted by a curve automatically according to 

the act working condition. Thus SiC heating elements have been widely applied in the fields of national 

defense, machinery, metallurgy, light chemical, ceramics, semiconductors, laboratory analysis, scientific 

research, etc. It has become ideal heating elements of all kinds of electric kiln furnace, such as, tunel 

kiln, roller kiln, glass furnace, vacuum furnace, muffle furnace, smelting furnace, etc.

Physical properties

SiC heating elements are hard and brittle, resistant to quick heating and cooling, not easy to deformation 

in high temperature. Other physical properties are as follows:

Density: 3.2 g/cm3

Moh's hardness: 9.5

Specific heat: 0.17 KCal/kg.C

Thermal conductivity: 20Kcal/m.hours.degrees 

Coefficient of linear expansion: 5x10-6 m/ .C

Chemical properties

SiC heating elements have a good chemical stability and strong acid resistance. Under high temperature 

condition, it can be eroded by alkaline substance. 

When you place an order, please clarify the items below:

Type: GD/GC/U/W/SG/SD

OD: Diameter; HZ: Length of the hot zone; CZ: Length of the cold zone; OL: Overall length 

If type U or type W, please mark terminal distance A. If you have special requirements about resistance, 

please inform resistance value.

 

Oder sample: 

GDD type, OD=14mm, HZ=150mm, CZ=100mm, OL=350mm, Resistance=1.5ohms.

Please specify as: GDD dia8/14x150x350mmx1.5ohms
