The higher temperature sintered silicon carbide product XICAR (normally called Hexoloy SE alternate) has established itself hugely immune to chemical corrosion in acidic environments like concentrated HCl and HNO3, with specimens treated with Y2O3 obtaining higher resistance than All those utilizing MgO sintering assist.
