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.

Ceramic liner and method of forming

A refractory article can include a body including a content of alumina of at least 60 wt %, a content of silica of not greater than 20 wt %, a content of zirconia of not greater than 20 wt % for a total weight of the body. In a particular embodiment, the body includes a third phase including composite grains including mullite and zirconia. The third phase including the composite grains can be present within a range including at least 1 wt % and not greater than 35 wt % for a total weight of the body.

Refractory articles and methods for forming same

A pipe choke for use in drilling and mining operations comprising a body including a first end and a second end configured to couple to a pipe, an opening extending through the body from the first end to the second end, and wherein the body includes a first phase comprising recrystallized silicon carbide and a second phase comprising silicon.

Construction articles and methods of forming same

A composite article including a body made of recrystallized silicon carbide and an infiltrant, wherein the body comprises a static impact resistance of at least about 1800 MPa.

Infiltrated silicon carbide bodies and methods of making

A composite article having a body including a first phase that includes a nitride material, a second phase that includes a carbide material, and a third phase having one of an amorphous phase material with a nitrogen content of at least about 1.6 wt % or an amorphous phase material comprising carbon.

Composite body including a nitride material, a carbide material, and an amorphous phase material

An article including a monolithic crucible body comprising silicon oxynitride (SiNO, wherein x&#x3e;0 and y&#x3e;0), wherein the silicon oxynitride extends throughout the entire volume of the monolithic crucible body.

Crucible body and method of forming same

A reaction sintered silicon carbide-based product, including a silicon carbide component, a bond component, wherein the bond component includes silicon oxynitride in excess of any silicon nitride of the bond component, and at least one boron component residual to an amount present prior to reaction sintering to cause increased resistance of the reaction sintered silicon carbide-based product to volume change under oxidative stress, and methods of making the same.

Volume-change resistant silicon oxy-nitride or silicon oxy-nitride and silicon nitride bonded silicon carbide refractory

Method of producing aluminum

Cryolite resistant refractory liner

There is provided a sidewall lining for use in an electrolytic reduction cell for the production of aluminum by reduction of alumina in a molten fluroide electrolyte, the lining consisting essentially of a ceramic material having a density of at least 95% of theoretical density and at least closed porosity, the ceramic material selected from the group consisting of silicon carbide, silicon nitride and boron carbide.
