It was nevertheless unavoidable that the low electrical conductivity of the barrier fluid would lead to oxidation of the silicon carbide and thus to the destruction of the sliding faces. The challenge for EagleBurgmann now was to optimize the seal face and the seat made of the FDA-compliant material silicon carbide on the product side.
Pure CVD silicon carbide wafer carriers | Engineer Live
By comparison, sintered SiC’s thermal conductivity is 100-140 watts per meter kelvin and pure graphite is typically only 85 watts per meter kelvin. CVD SiC’s higher thermal conductivity results in a uniform temperature across the wafer’s entire diameter, improving the GaN deposition process and significantly increasing production yields, compared to coated graphite wafer carriers.

Silicon: Here are 5 Underappreciated Facts
Silicon is a meer of the periodic table of elements. Pretty much all of us know that from our high-school chemistry classes. It is a natural mineral and element (as opposed to lab-formed elements similar to what is seen at the bottom of the periodic table) that is
Silicon Windows - Zygo Corporation
Silicon has an advantage over other IR materials due to its low density (about half that of Zinc Selenide or Germanium), making it ideal for optical systems where weight is a significant factor. Silicon windows are also more robust and less brittle than Germanium windows , and have high thermal conductivity.
