Inquiry (采购产品): coatings for carbon forms We use machined carbon forms to support metal pins during the fusing of glass to the pins at about 1850 degrees F. Over time loose carbon particles develop and contaminate the product. I'm looking for an inexpensive alternate to these carbon forms. Material requirements are: a. must be machinable, b. must survive many thermal cycles between room temperature and 1850 F in a nitrogen or forming gas atmosphere, c. must not stick to molten glass (barium alkali silicate eg. Corning 9013, Electro-glass 2164 or similar). Instead of an expensive, pure material like boron nitride, and alternative might be to stick with machined carbon forms, but coat them with some material that seals them. I was wondering if you offered any coatings for carbon that might meet these requirements. I've heard of silicon carbide as a coating for graphite, but worry that it might stick too well to our glass. Are there some other reasonably priced alternatives?
