Abstract

A refractory assembly for containment of molten aluminum-lithium alloys, comprising a nitride bonded silicon carbide refractory brick and a seam joined to the brick. The seam is formed from a mortar mix comprising particulate nitride refractory filler and colloidal sol binder. The brick and seam both exhibit good resistance to attack by molten aluminum-lithium alloys at elevated temperatures.
