I am interested in carrying out a hydrothermal reaction at 500C. But for that I can't use a teflon lined reactor as it can withstand a maximum temperature of 200C. As per literature, they are using the term hastelloy reactor. I need info on this, i.e the cost, suppliers, specifically an image of how it looks and how is it different in design apart from the material. I did a search online, but not convinced enough.
