Abstract:
A solid electrolyte contains an internal component and an external component coated on a surface of the internal component. The internal component is represented by a formula Li 1+x M x Zr 2-x (PO 4 ) 3 , M is one or more elements selected from a group consisting of Al, La, Cr, Ga, Y, and In, and 0.05≤x≤0.4. The external component contains a plastic deformable material and has a conductivity of about 10 -7 S/cm to about 10 -5 S/cm. A method of preparing the solid electrolyte and a lithium ion battery including the solid electrolyte are also provided.
Abstract:
A process is described, for producing zirconia-based multi-phasic ceramic composite materials, comprising the steps of: providing at least one ceramic suspension by dispersing at least one ceramic zirconia powder in at least one aqueous medium to obtain at least one matrix for such composite material; providing at least one aqueous solution containing one or more inorganic precursors and adding such aqueous solution to such ceramic suspension to surface modify such ceramic zirconia powder and obtain at least one additived suspension; quickly drying such additived suspension to obtain at least one additived powder; heat treating such additived powder to obtain at least one zirconia powder coated on its surface by second phases; and forming such zirconia powder coated on its surface by second phases.
Abstract:
Provided are chemical compositions including Ni, at least one promoter and yttria-stabilized zirconia. The promoter, such as BaO, may be selectively associated with the Ni portion of the composition. Also are provided are processes for making the chemical compositions.
Abstract:
Methods are described to make strong, tough, and/or lightweight glass-ceramic composites having a crystalline phase and an amorphous phase generated by viscous reaction sintering of a complex mixture of oxides and other materials. The present invention further relates to strong, tough, and lightweight glass-ceramic composites that can be used as proppants and for other uses.

Abstract:
A bonded abrasive wheel comprises ceramic shaped abrasive particles retained in a binder. The ceramic shaped abrasive particles are bounded by a respective base, top and plurality of sides connecting the base and the top. Adjacent sides meet at respective side edges having an average radius of curvature of less than 50 micrometers.
Abstract:
A composition includes a carbon nanotube (CNT)-infused ceramic fiber material, wherein the CNT-infused ceramic fiber material includes: a ceramic fiber material of spoolable dimensions; and carbon nanotubes (CNTs) bonded to the ceramic fiber material. The CNTs are uniform in length and uniform in distribution. A continuous CNT infusion process includes (a) disposing a carbon-nanotube forming catalyst on a surface of a ceramic fiber material of spoolable dimensions; and (b) synthesizing carbon nanotubes on the ceramic fiber material, thereby forming a carbon nanotube-infused ceramic fiber material.
