Technological Properties of SiC-Based Ceramic Slurries for Manufacturing Investment Casting Shell Moulds

open access: yesArchives of Metallurgy and Materials, 2014
Abstract In this work technological properties of ceramic slurries based on silicon carbide were characterized. Silicon carbide and poly(vinyl alcohol) in an amount 6%, 10% and 15 wt. % as a solution were added to prepare the ceramic slurries. Solid phase content in ceramic slurries was 62, 5 wt.%. Plate weight test, pH, density, viscosity (measured by
