Abstract
A foundry mould binder comprises a mixture of 90-95% by weight of an alkali-metal-silicate having a silica to alkali-metal-oxide weight ratio within the range 2-3.22, and 5-10% by weight of a material capable of forming ammonia in situ when heated. The ammonia-forming material may be urea and the alkali metal silicate, sodium silicate and the moulds or cores may be hardened by a gaseous material such as CO2. The subjectmatter of the Specification, apart from some specific examples is included in Specification 847,477 which is referred to.
