Patent number: 9968941Abstract: A method of preparing an aluminum metaphosphate (ALMP) particulate product includes charging a milling chamber of a ball mill with grinding media and loading an ALMP feedstock into the milling chamber. The ALMP feedstock is milled with the grinding media into ALMP particles at a particle reduction index in a range from 0.25 to 0.5. At a plurality of time steps during a period in which the milling is carried out, a fine fraction of the ALMP particles is removed from the milling chamber while a coarse fraction of the ALMP particles remains in the milling chamber for additional milling. An ALMP particulate product with a particle size distribution having a median particle size in a range from 100 ?m to 700 ?m is prepared from the ALMP particles removed from the milling chamber.Type: GrantFiled: May 28, 2015Date of Patent: May 15, 2018Assignee: CORNING INCORPORATEDInventors: Kimberly Errin Hill, Martin Joseph Murtagh

Publication number: 20090298670Abstract: A method of removing graphite from a core region of a cordierite-forming green body and a method of firing a cordierite-forming green body to form a fired cordierite body. A dried cordierite-forming green body containing graphite is first heated so that the core region is at a first temperature in a range from about 950° C. up to about 1100° C. The green body is then either held at the first temperature or heated to a second temperature in a range from about 1050° C. up to about 1160° C.; in either case resulting in removal of a majority of graphite from the core region. The green body may then be heated to a third temperature in a range from about 1300° C. up to about 1350° C. at a second predetermined heating rate to remove any residual graphite from the core region and then heated to a temperature of at least 1390° C. to form the fired cordierite body.Type: ApplicationFiled: June 27, 2008Publication date: December 3, 2009Inventors: Martin Joseph Murtagh, Mark Allen Spetseris, Doug Wing
