Effect of AlF3·3H2O addition on microstructure and properties of ceramic shell for investment casting

Using fused corundum powder as raw material， silica sol as a binder， and aluminum fluoride trihydrate as mullite phase conversion promoter， the slurry composition of the ceramic shell for directional solidification molding of turbine blades was designed， and the ceramic shell was prepared. The micro...
