  • Patent number: 6365568
    Abstract: The invention includes a process for manufacturing an improved solid cast alkaline composition, that includes (a) reacting an alkali metal silicate with an alkali metal hydroxide of the formula MOH, where M is an alkali metal, in an aqueous environment to form a reaction product; and (b) solidifying the reaction product in a mold where the reaction product is formed and solidified at room temperature without the addition of externally supplied heat and the reaction product solidifies without the use of external cooling; and where the relative amount of alkali metal silicate, alkali metal hydroxide and water incorporated into the composition are effective for producing a reaction product having about 20 to 50 parts water per 100 parts of a combination of the alkali metal silicate, the alkali metal hydroxide and water in the cast solid composition and an M2O:SiO2 ratio of about 2.5:1 to 4.
