13470-38-7 - Uses and synthesis methods
application
In the ceramic field, yttrium iodide can be used in abrasives, bearings and seals, high temperature refractory materials for continuous casting gates, spray paint engine coatings, engine oxygen sensors and wear and corrosion resistant cutting tools.
Preparation
Pass the mixture of hydrogen iodide and hydrogen into yttrium chloride, and iodinate it at 600°C. After the reaction is complete, change to helium to remove the adsorbed gas, or dissolve yttrium oxide in hydroiodic acid, Then add ammonium iodide, and then add concentrated hydroiodic acid.
