High-purity periclase-spinel refractories impregnated with different types of impregnates have been tested for cement clinker resistance. The depth and degree of products impregnation have been determined. The change in the structure of refractory materials after testing has been investigated. It was established that impregnation of crucibles with aluminum-containing or carbon-containing agents slows down the penetration of aggressive components into the product, reducing the depth and area of impregnation. The positive effect of impregnation on the clinker resistance of refractories of periclase-spinel composition has been confirmed.
