The disclosure provides seals for devices that operate at elevated temperatures and have reactive metal vapors, such as lithium, sodium or magnesium. In some examples, such devices include energy storage devices that may be used within an electrical power grid or as part of a standalone system. The energy storage devices may be charged from an electricity production source for later discharge, such as when there is a demand for electrical energy consumption.

The present invention relates to a method for making a hexagonal boron nitride slurry and the resulting slurry. The method involves mixing from about 0.5 wt. % to about 5 wt. % surfactant with about 30 wt. % to about 50 wt. % hexagonal boron nitride powder in a medium under conditions effective to produce a hexagonal boron nitride slurry. The present invention also relates to a method for making a spherical boron nitride powder and a method for making a hexagonal boron nitride paste using a hexagonal boron nitride slurry. Another aspect of the present invention relates to a hexagonal boron nitride paste including from about 60 wt. % to about 80 wt. % solid hexagonal boron nitride. Yet another aspect of the present invention relates to a spherical boron nitride powder, a polymer blend including a polymer and the spherical hexagonal boron nitride powder, and a system including such a polymer blend.

An abrasive article includes a body having abrasive particles contained within a bond material. The abrasive particles can include a majority content of silicon nitride and a minority content of sintering material including at least two rare-earth oxide materials. In an embodiment, the rare-earth oxide materials can include NdOand YO. In a particular embodiment, the abrasive particles comprise a content (wt %) of NdOthat is greater than a content of YO(wt %).

Abrasive articles including abrasive particles of silicon nitride

Method and system for bonding two or more CVD SiC articles together without the use of interface materials using applied forces from about 0.0035 MPa to about 0.035 MPa. The articles are pretreated for bonding. Graphite or other fixtures are used to apply forces in a vacuum or inert gas environment. Temperatures from about 1900&#xb0; C. to about 2200&#xb0; C. are used to initiate a &#x3b2;&#x2192;&#x3b1; transition in the SiC to create bonded CVS SiC articles.

A method of preparing an article includes compressing a polymeric material to form a body and hot isostatic pressing (HIP) the body in an inert atmosphere at a pressure of at least 3 ksi without an encapsulant. The body may optionally be sintered prior to hot isostatic pressing (HIP). The body may have a porosity of not greater than 8% prior to hot isostatic pressing (HIP). The polymer material may be a non-melt processible polymer.

The present invention relates generally to a multi-layered article suitable for service in severe environments. The article may be formed of a substrate, such as silicon carbide and/or silicon nitride. The substrate may have a first layer of a mixture of a rare earth silicate and Cordierite. The substrate may also have a second layer of a rare earth silicate or a mixture of a rare earth silicate and cordierite.

A densified silicon nitride body can be formed using a lanthana-based sintering aid. The composition may exhibit properties that provide a material useful in a variety of applications that can benefit from improved wear characteristics. The composition may be densified by sintering and hot isostatic pressing.

In a method of preparing a boron carbide material, boron carbide powder is washed with essentially pure water at an elevated temperature to generate washed boron carbide powder. The washed boron carbide powder is combined with a sintering aid. The mixture of the boron carbide powder and the sintering aid is pressed to form a shaped material, and the shaped material is sintered. A sintered boron carbide material comprises a boron carbide component that includes boron carbide, elemental carbon, and not more than about 0.6 wt % of oxygen on the basis of the total weight of the boron carbide component. The sintered boron carbide material has a density of at least about 99% of the theoretical density. Another sintered boron carbide material comprises a boron carbide component that includes boron carbide, silicon carbide, elemental carbon, and not more than about 0.3 wt % oxygen on the basis of the total weight of the boron carbide component, and has a density of at least about 97% of the theoretical density.
