High thermal conductivity:

The thermal conductivity of SiC is 140 W/mK, twice that of modified graphite, 2.5 times that of tantalum, 5 times that of stainless steel, 15 times that of enamel and 20 times that of Teflon.

• Less heat transfer area   • Smaller heat exchanger size

 

High corrosion resistance:

 

Corrosive Medium Temperature ˚C Corrosion Rate (mg/cm2 years)
98% H₂SO₄ 100 1.8
85% H3SO₄ 100 <0.2
54% HF 25 <0.2
50% NaOH 100 2.5
45% KOH 100 <0.2
70% HNO3 100 <0.2
37% HCl 86 <0.2
10% HF and HNO3 25 <0.2

 

• The only ceramic material resistant to hydrofluoric acid corrosion
• Resistant to high concentration of nitric acid, sulfuric acid, mixed acid, alkali, oxidant and organic chloric acid.
