YM NANO SILICA

Precision Investment Casting

This is a classic application for ammonium stabilization, leveraging its volatility at high temperatures to avoid casting defects.

· Binder for Shell Building

   · Common Type: Alkaline, Ammonium-stabilized (Core requirement).

   · Solid Content: 30% - 31% (Standard concentration for casting).

   · Particle Size: 10-20 nm.

   · Function & Principle: Binds refractory materials (like zircon flour) to form a solid shell. During high-temperature dewaxing, the ammonium volatilizes without residue, preventing shell cracking.
