Need help making a high temp pigment

[QUOTE="hygume, post: 6853648, member: 661734"] I'll spare y'all the details but, in short, instead of previous plans I'd had, I've ended up doing exciting engineering work for a company in Virginia. Our products operate in very high-temperature environments (>1000C) routinely and we like to dye them black for visual appeal. As we look towards higher temp applications, our current dye will be insufficient. I'm looking to utilize graphite as the base of our pigment but, the pH is too acidic (~5, needs to be closer to 8-8.5). I'm an engineer, and not the colloidal chemistry kind. Would a simple alkaline wash be sufficient to maintain the desired pH? If I were to mix with an inert base material so that the average pH were in that 8-8.5 range, would that achieve the sort of results we're looking for? I apologize for the likely amateur questions but, I forgot all of ORGO the moment I finished the final exam. Thanks in advance for any help y'all can provide! [/QUOTE]
