Silicon Carbide(SiC) has become a popular keywords in semiconductor industries.
Few years back, we received inquiries from our clients to measure thermal conductivity of SiC.
Back then, they were under the research and development.
But now, they have been mass produced.
We were astonished by the speed of R&D on SiC.
The thermal property of SiC is not good as diamonds, but higher than normal metals.
i.e. about 100 to 350 [W/mK]
The applications of SiC are written in wikipedia.
1 Abrasive and cutting tool
2 Structural material
3 Automobile parts
4 Electric systems
5 Electronic circuit elements
6 Astronomy
7 Thin filament pyrometry
8 Heating elements
9 Nuclear fuel elements
10 Jewelry
11 Steel production
12 Catalyst support
13 Carborundum printmaking
14 Graphene production
Today, I would like to share the results of 6H-SiC which were measured with Thermowave Analyzer (TA) with you.
Thermal conductivity is about 350 [W/mK]
Thermal conductivity is calculated from thermal diffusivity, density, and heat capacity.
The values for density and heat capacity were found in literature.
We also measured different crystalline of 4H-SiC and 6H-SiC.
The results on these SiC were higher than 350 [W/mK].
We don't know why the results were higher but reason must be due to how SiCs were produced.
Anyway, if you want to evaluate your SiC, please feel free to contact us.

A heating element converts electricity into heat through the process of Joule heating. Heating elements for high-temperature furnaces are often made of exotic materials, including platinum, molybdenum disilicide, molybdenum (vacuum furnaces) and silicon carbide. Igniters of SIC heating element are common in gas ovens. If anyone looking for packaging machines buy at Silcarb
Silicon Carbide Heating Element,
A silicon carbide (SiC) heating element (Fig. 1) is typically an extruded tubular rod or cylinder made from high-purity grains of silicon carbide that are fused together by either a reaction-bonding process or a recrystallization process at temperatures in excess of 3900°F (2150°C). The result is a chemically stable material with a low thermal-expansion coefficient and little tendency to deform.
