Patent number: 9074124Abstract: Disclosed is a population of ceramic particles that includes a plurality of individual, free flowing particles. The plurality has a total weight and particle size distribution. The effective width of the distribution is the difference between the distribution's d95 and d5 particle sizes. The distribution's effective width exceeds 100 microns and includes three abutting and non-overlapping regions that include a first region, a second region, and a third region. The first region abuts the second region and the second region abuts the third region. The width of the second region is at least 25% of the effective width. The weight of particles in the second region does not exceed 15% of the plurality of particle's total weight. The weight of particles in the first region and the third region each exceed the weight of particles in the second region. Methods of making the populations of ceramic particles are also disclosed.Type: GrantFiled: February 8, 2011Date of Patent: July 7, 2015Assignee: Saint-Gobain Ceramics & Plastics, Inc, Inc.Inventors: Walter T. Stephens, Kevin R. Dickson, Tihana Fuss, Ian Jaeger, Danny Louis Mickelson, Suchira Sen, Thomas Szymanski

Publication number: 20140374938Abstract: Disclosed is a process for producing ceramic particles, such as proppants, that have at least 10 percent total porosity. The process includes forming a particle precursor that includes 5 percent to 30 percent of a first ceramic material and at least 40 percent of a second ceramic material. The sintering temperature of the first ceramic material may be lower than the sintering temperature of a second ceramic material. Heating the precursor to a maximum temperature above the sintering temperature of the first material and below the sintering temperature of the second material. Also disclosed is a ceramic article that has a particular combination of chemistry and alumina crystalline phase.Type: ApplicationFiled: June 25, 2013Publication date: December 25, 2014Inventors: Tihana FUSS, Laurie San-Miguel, Kevin R.

Patent number: 6757963Abstract: A surface of a first ceramic component is joined to a surface of a second ceramic component using a silver-based composition. The silver-based composition is a mixture of silver metal and a metal oxide and the metal in the metal oxide is a metal other than silver. The silver-based composition is applied to the surface of the first ceramic component and to the surface of the second ceramic component. The silver-based composition applied to the first ceramic component is contacted to the silver-based composition applied to the second ceramic component. The surfaces of the first and second ceramic components are heated to melt the applied silver-based compositions. The surfaces of the first and second ceramic components are cooled to form a bond between the first and second ceramic components.Type: GrantFiled: January 23, 2002Date of Patent: July 6, 2004Assignee: McGraw-Edison CompanyInventors: Alan M.
