AI Technical Summary
Silicon nitride slurry has problems with substandard dispersibility and imbalance of powder material ratio during preparation, which leads to abnormalities such as bumps, lines, holes, cracks and indentations in the product, affecting product yield and quality.
Silicon nitride slurry was prepared by ball milling using silicon nitride powder of a specific shape, organic adhesive of a specific molecular weight, and block polymer as dispersants. Combined with the synergistic dispersing effect of linseed oil and block polymer, a stable bonding network was formed, which improved the fluidity and dispersibility of the slurry.
It significantly improves the dispersibility and stability of silicon nitride slurry, reduces product defects, and enhances the product qualification rate and casting effect during the production process.
