ABSTRACT:
The invention is directed to a low density material suitable for use as an expendable liner in a molten metal handling vessel such as tundish. The low density materials include a first component having at least one decomposable compound capable of producing gas, a second component having a reactable compound for reacting with the decomposable compound in the presence of water to cause the decomposable compound to generate a gas, and a refractory aggregate. The invention also relates to a method for making the low density material and to the resultant material as well.
