In most cases, alteration to catalyst structure is permanent and the resultant loss in activity is irreversible. Catalyst sintering can be avoided by controlling the temperature of the burn front during the catalyst regeneration process. If the temperature gets too high, there can be localised sintering of the base, causing a loss of surface area.
