  • Ceramic liner and method of forming
    Patent number: 11181321
    Abstract: A ceramic liner can include a monolithic body having a surface portion and a bulk portion. The surface portion can have a thickness less than the total thickness of the monolithic body. The monolithic body can include an amorphous phase. The amorphous phase can be discontinuous. At least one member of the discontinuous phase can be embedded in the surface portion. The bulk portion can be substantially free of the amorphous phase. A method of forming a ceramic liner can include providing a furnace with a coating and a bulk material of the ceramic liner and heating the bulk material and the coating. In an embodiment, a coated lining form can be used to provide the coating. In a particular embodiment, the coating can be transferred to the bulk material from the coated lining form.
