  • Patent number: 11376822
    Abstract: A corrosion-resistant component configured for use with a semiconductor processing reactor, the corrosion-resistant component comprising: a) a ceramic insulating substrate; and, b) a white corrosion-resistant non-porous outer layer associated with the ceramic insulating substrate, the white corrosion-resistant non-porous outer layer having a thickness of at least 50 ?m, a porosity of at most 1%, and a composition comprising at least 15% by weight of a rare earth compound based on total weight of the corrosion-resistant non-porous layer; and, c) an L* value of at least 90 as measured on a planar surface of the white corrosion-resistant non-porous outer layer. Methods of making are also disclosed.

  • Publication number: 20190331243
    Abstract: A drill piping or tubing pressure seal includes a diameter-spanning body portion. The diameter-spanning body portion includes a high-pressure side, a low-pressure side and a plug receptacle passing through the diameter-spanning body portion from the high-pressure side to the low-pressure side. The high-pressure side and the low-pressure side of the diameter-spanning body portion include a protective coating; however, an interior surface of the plug receptacle located between the high-pressure side and the low-pressure side does not include the protective coating. In addition, a plug is configured to be located within the plug receptacle, and the plug is configured to be retained within the plug receptacle by an anchor element to maintain the plug within the plug receptacle until a breakaway force of the anchor element is exceeded. A gasket is located between a portion of the plug and the plug receptacle.

  • Patent number: 10305116
    Abstract: The present invention relates to a protonic ceramic fuel cell and a method of making the same. More specifically, the method relates to a cost-effective route which utilizes a single moderate-temperature (less than or equal to about 1400° C.) sintering step to achieve the sandwich structure of a PCFC single cell (dense electrolyte, porous anode, and porous cathode bone). The PCFC layers are stably connected together by the intergrowth of proton conducting ceramic phases. The resulted PCFC single cell exhibits excellent performance (about 450 mW/cm2 at about 500° C.) and stability (greater than about 50 days) at intermediate temperatures (less than or equal to about 600° C.). The present invention also relates to a two step method for forming a PCFC, and the resulting PCFC.

  • Patent number: 10000422
    Abstract: The present invention provides a ceramic to ceramic joint and methods for making such a joint. Generally, the joint includes a first ceramic part and a second ceramic part, wherein the first and second ceramic parts each include a ceramic-carbide or a ceramic-nitride material. In some cases, an aluminum-initiated joint region joins the first and second ceramic parts. This joint region typically includes chemical species from the first and second ceramic parts that have diffused into the joint region. Additionally, the first and second ceramic parts each typically include a joint diffusion zone that is disposed adjacent to the joint region and which includes aluminum species from the joint region that have diffused into the joint diffusion zone. Other implementations are also described.

  • Patent number: 9975811
    Abstract: A sintered ceramic ball is described that includes an incomplete ceramic ball portion with a wall with an exterior surface, the wall having an interior space located radially interior of an inner surface of the wall. The incomplete ceramic ball portion also has an exterior surface, the exterior surface having an exterior surface area. The sintered ceramic ball further includes a ceramic plug joined with the incomplete ceramic ball portion to form a continuous exterior ball surface. The ceramic plug includes an exterior plug surface and a plug wall. The plug surface includes an exterior plug surface area, wherein the exterior plug surface area is between about 5% to 49.9% of the sum of the exterior surface area of the incomplete ceramic ball portion and the exterior plug surface area. The interior space of the sintered ceramic ball is sealed within the wall and the plug wall.

  • Patent number: 9285120
    Abstract: An igniter shield for use in combination with an igniter includes a substantially cylindrical-shaped body that includes a proximal portion, a distal portion, a first longitudinally oriented support and a second longitudinally oriented support wherein the first and second longitudinally oriented supports extend between and are connected to the proximal portion and the distal portion, the substantially cylindrical-shaped body further including a longitudinally oriented baffle circumferentially spaced apart from the first and second longitudinally oriented supports, wherein the baffle extends between and is connected to the proximal portion and the distal portion, and wherein the baffle includes a radially outward facing convex surface and a radially inward facing concave surface, the radially inward facing concave surface having a radius of curvature smaller than a radius of curvature of at least one of the proximal or distal portions.
