Binder composition which comprises:
- A. boronated aluminum phosphate containing boron in an amount from about 3 mole % to about 40 mole % based upon the moles of aluminum and containing a mole ratio of phosphorus to 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 the aluminum phosphate and which contains alkaline earth metal and an oxide;
- and
- C. water;
- wherein the amount of boronated aluminum phosphate is from about 50 to about 95% by weight based upon the total weight of aluminum phosphate and alkaline earth compound;
- the amount of alkaline earth compound is from about 50 to about 5% by weight based upon the total weight of aluminum phosphate and alkaline earth compound;
- and the amount of water is from about 15 to about 50% by weight based upon the total weight of boronated aluminum phosphate and water.
