Refractory temperature of Bentonite
Artificial sodium bentonite with sodium condition, temperature is not a failure, but lower than the natural sodium bentonite; expansion force of natural sodium bentonite than artificial Na bentonite; natural sodium base bentonite artificial Na bentonite c axis high degree of order, grain is fine, strong dispersion.
The failure temperature of natural sodium based bentonite is 638, and that of calcium bentonite is 316.
