CVD, CVI, FIC, IVD, slurry coatings, and thermal purification vacuum furnaces.

CVI (Chemical Vapor Infiltration) furnaces are special solutions used in the CVI process, which is a technique for producing carbon materials, such as graphite, by saturating them with carbon from the gas phase.  They are designed to enable controlled deposition of carbon layers on porous materials. 

CVD (Chemical Vapor Deposition) furnaces are special furnaces used in the CVD process, which is a technique for producing coatings through chemical reactions in the gas phase, e.g. from MTS (CH3SiCl3-Methyltrichlorosilane gas).
They are designed to enable controlled deposition of materials on the surface of the processed materials.  

Purification furnaces using gases such as hydrogen chloride (HCl) are used to purify graphite materials.
