White or Light pink sphere,insoluble in water and organic solvent. Soluble in strong acidic and alkalinesolutions, Moisture adsorptive in air, not expanding and cracking afteradsorbing water. With the charaters of high strength, resistance to sulfate poisoningand good thermal stability.  It is animproved Sulfur-Recovery Catalyst, the sulfate poisoning resistance, theactivity and stability after aging treatment are better than the AL2O3 catalystused in the industries nowdays. 

Used as catalyst in the Klausrecovering technology in oil refinery with H2S acidic gas, natural gasde-sulfur, city coal-gas and petrochemical industries.
