Abstract
A receiver for casting molten material formed by the steps comprising forming a mixture comprising particulate ceramic powders and a binder; adding the mixture to a mold disposed to form board-like members and hardening the mixture; removing the hardened mixture from the mold; reducing the permeability of the board-like members, cementing the board-like members together to form a receiver and coating the receiver with release agents. Specifically, the receivers are used in the casting of high purity silicon for solar energy cells.
