Abstract
A process for the manufacture of a foundry form comprising: A) mixing a foundry aggregate with a consolidation amount of up to about 10% by weight based on the weight of the aggregate of the binder composition comprising: a) Borated aluminum phosphate containing boron in an amount of from about 3 mol% to about 40 mol% based on the moles of aluminum and containing a molar ratio of phosphorus to the total moles of aluminum and boron of about 2: 1 to about 4: 1, b) an oxygen-containing alkaline earth metal compound capable of reacting with aluminum phosphate and containing alkaline earth metal and an oxide; and c) water, wherein the amount of borated aluminum phosphate is from about 50 to about 95% by weight based on the total weight of the aluminum phosphate and the alkaline earth compound; the amount of alkaline earth compound is from about 50 to about 5% by weight based on the total weight of the aluminum phosphate and the alkaline earth compound and the amount of water is from about 15 to about 50% by weight based on the total weight of borated aluminum phosphate and where the quantity and particle size of said aggregate are such that they provide sufficient porosity in the casting form to allow the escape of volatile gases from the casting during casting. B) introduce the foundry mixture obtained in step (A) in a mold. C) allowing the foundry mix to sit in the mold long enough for the mix to be consistent, and D) then remove the patterned cast mixture from step (C) from the mold and allow it to cure at room temperature, thus obtaining a strong, solid and cured cast shape.
