20140134097 | MAGNESIUM OXIDE POWDER HAVING EXCELLENT DISPERSIBILITY AND METHOD FOR PRODUCING THE SAME - A magnesium oxide powder having excellent dispersibility and a small average particle diameter as well as a uniform particle diameter and containing no very small size particles is obtained. A magnesium oxide powder which is particles, wherein the magnesium oxide powder has a BET specific surface area of 5 m | 05-15-2014 |
20130224421 | SINTERED MAGNESIUM OXIDE MATERIAL, AND PROCESS FOR PRODUCTION THEREOF - Disclosed herein are a sintered magnesium oxide material which is capable of suppressing the occurrence of splashing during film formation and which is less likely to cause clogging of a supply inlet of a film formation device, a deposition material for PDP-protecting film using the same, and a process for producing the sintered material. The sintered magnesium oxide material contains magnesium oxide, 3 to 50 mass % of an oxide of a Group 2A element other than magnesium in the periodic table, and if necessary, 1000 ppm or less of one or two or more elements selected from the group consisting of aluminum, yttrium, cerium, zirconium, scandium, and chromium, and has a disk-like, elliptical plate-like, polygonal plate-like, or half-moon-like shape or a cubic or rectangular solid shape with rounded apexes. | 08-29-2013 |
20120189850 | MAGNESIUM OXIDE POWDER HAVING EXCELLENT DISPERSIBILITY AND METHOD FOR PRODUCING THE SAME - A magnesium oxide powder having excellent dispersibility and a small average particle diameter as well as a uniform particle diameter and containing no very small size particles is obtained. A magnesium oxide powder which is particles, wherein the magnesium oxide powder has a BET specific surface area of 5 m | 07-26-2012 |
20100266845 | Magnesium Oxide Powder - Magnesium oxide powders having a large diameter of crystallite, and having a favorable crystallinity are provided. Magnesium oxide powders: having peak widths at half-height of the peaks on a (111) plane, a (200) plane and a (220) plane of each no greater than 0.20 degrees as determined with a powder X-ray diffraction method carried out using a Cu—Kα ray; and having a crystallite diameter of no less than 700 Å. | 10-21-2010 |
20100183877 | MAGNESIUM OXIDE PARTICLE AGGREGATE AND METHOD FOR PRODUCING THE SAME - The object is to provide a high-purity magnesium oxide particle aggregate that is redispersible and can be supplied with keeping high purity, and a method for producing the same. | 07-22-2010 |
