Selection considerations
What the furnace does
A silicon carbide coating protects graphite parts from the hot, reactive atmosphere inside crystal growth and other high-temperature tools, and limits particles and carbon released into the process. The VERAL GH from NAURA coats graphite components and SiC substrates with silicon carbide by chemical vapour deposition. It sits in the parts supply chain behind wafer processing: coated parts go into crystal growth components for crystal growth furnaces, and into carriers among process graphite parts used by cell lines.
Send drawings of your largest and most complex parts and agree how they will be loaded and fixed in the chamber, because fixturing decides which surfaces receive coating and where contact marks fall. Define the coating targets: thickness at named points, coverage inside holes and slots, and the surface finish your users need. Settle precursor gas delivery, exhaust treatment and safety interlocks, and which side supplies each; the guide to utilities and installation lists the interfaces to fix in the contract. Ask how often the chamber and its own fixtures must be cleaned or replaced, and what that adds to each run.
Accepting the furnace
Accept on coated parts from a fully loaded run rather than a single test piece. Section sample parts to measure thickness, check coverage and adhesion after a heat cycle, and repeat across several runs to see run-to-run variation. The guide to trials, FAT and SAT helps you split checks between the maker's site and yours. Keep recipe, load map and part results together for each run.
Plan the equipment scope
Identify the production step, cell or module format and output unit before comparing equipment. Use the listed source, scope and specifications to prepare a configuration-specific enquiry. Missing values are left unspecified and do not count as exact filter matches.
NAURA's VERAL GH is a CVD furnace that lays a semiconductor-grade silicon-carbide coating on graphite parts and SiC substrates. The product page lists a 1600°C maximum temperature, ±10°C uniformity and a 10 Pa cold ultimate vacuum, with liquid and solid feed arrangements. It suits buyers of coated graphite components; send part drawings and coating targets to get a quote.
