The core mechanism of xanthan gum's role in refractory materials is physical bonding and high-temperature volatilization, meaning it bonds refractory particles through intermolecular forces at room/medium temperatures, providing body strength. It completely decomposes without residue during high-temperature sintering, without affecting the final properties of the refractory material. The core use of xanthan gum in refractory materials is as a temporary binder.

Primarily enhances the strength of refractory bodies during drying and handling, preventing cracking or disintegration.
