    摘要： A smokable product based on cellulose and combustion-modifying substances, containing(a) 0.1-10% by weight, based on the total weight of the smokable product, of finely divided solids, the average particle diameter of which is less than 2.mu., in a distribution which is heterogeneous over the cross-section of the smokable product, with an enrichment in or on the surfaces, and(b) 0.5-15% by weight, based on the total weight of the smokable product, of salts of monobasic or polybasic carboxylic acids. The product being prepared by saturating, spraying or coating a combustible, prefabricated material which is based on cellulose and optionally contains fillers customarily used in smokable products and which can be used as a smokable product with a dispersion of solids, the average particle diameter of which is less than 2.mu., in a solution of salts of monobasic or polybasic carboxylic acids.
