Setter plates are fabricated from Li-stuffed garnet materials having the same, or substantially similar, compositions as a garnet Li-stuffed solid electrolyte. The Li-stuffed garnet setter plates, set forth herein, reduce the evaporation of Li during a sintering treatment step and/or reduce the loss of Li caused by diffusion out of the sintering electrolyte. Li-stuffed garnet setter plates, set forth herein, maintain compositional control over the solid electrolyte during sintering when, upon heating, lithium is prone to diffuse out of the solid electrolyte.

A mold assembly and method for molding two concrete blocks in face-to-face non-contacting relationship forms blocks having smooth front faces. The mold assembly includes a mold box having two mold cavities configured to form two blocks in face-to-face non-contacting relationship. A common partition plate separates the two mold cavities and opposite sides of the partition plate form the smooth front faces of the blocks. The two mold cavities are each configured to form a block having a raised front face with a beveled edge around its entire perimeter and a border around the entire perimeter of the beveled edge. The portions of the border at the top and the sides of the raised front face are curved and the portion of the border at the bottom of the raised front face is straight. A core bar is slidably inserted into the mold box beneath the bottom of the partition plate, and opposite sides of the core bar extend into and form the front bottom portions of the mold cavities.

The disclosure relates to methods of fabricating of ceramic structures, and more particularly to methods of fabricating ceramic structures having profiled surfaces and more particularly to methods of fabrication of ceramic mirror blanks. In one embodiment, a method of forming a shaped ceramic article, includes: forming, via one of a cold-pressing process or pressure casting process, a green ceramic article comprising a first surface, an opposing second surface and at least one high aspect ratio feature shaped into at least one surface; heating the green featured ceramic part to form a debound featured ceramic part; and densifying the debound featured ceramic part via one of a pressureless sintering process or a hot-pressing process.

A method for manufacturing a jewel for a timepiece, the jewel including, for example, poly-ruby of the Al2O3Cr type or Zirconia of the ZrO2 type, including first producing a precursor and a then pressing the precursor in order to form a body, the pressing being carried out using a pressing device provided with an upper die and a lower die defining a pressing space wherein the precursor is disposed, the upper die including a concave portion of oblong shape, the device having a wire at least partially traversing the lower die to open into the pressing space, the lower die being able to slide around the wire, the pressing being carried out by bringing the lower die and the upper die closer together to form a body including an upper face provided with a dome and a lower face provided with a hole extending at least partially into the dome.

Tooling assemblies and methods for using a tooling assembly to shape an article are provided. For example, a tooling assembly has a forward end and an aft end and comprises a first tool segment, a second tool segment, a forward cam portion near the forward end, and an aft cam portion near the aft end. The forward cam portion defines a follower surface, and at least a portion of the follower surface has a curvilinear profile. The aft cam portion defines a first surface extending at a first angle and a second surface extending at a second angle. The first and second tool segments define a cavity for shaping an article. An exemplary method comprises positioning an article preform within the cavity and inserting a fastener within the aft end of the tooling assembly until the fastener is fully inserted within the tooling assembly.
