Polycrystalline transparent spinel sinters

Polycrystalline transparent spinel sinters. Matsui, Minoru; Takahashi, Tomonori (NGK Insulators, Ltd., Japan). Ger. Offen. DE 3319346 A1 28 Jun 1984, 25 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C04B035-10. APPLICATION: DE 83-3319346 27 May 1983. PRIORITY: JP 82-232545 27 Dec 1982. DOCUMENT TYPE: Patent CA Section: 57 (Ceramics) Polycryst., transparent spinel sinters (with an in-line transmission of 77%/mm at a wavelength of 0.6m) are produced by hydrolyzing a mixt. of Al isopropoxide [555-31-7] and Mg isopropoxide [15571-48-9] in iso-PrOH at a mol. ratio of from 0..498 to 0..476, heating the ppt. to 900-1100°, molding the powder, and sintering at >1700° for >10 h. Thus, an Al2O3-MgO powder mixt. at a mol ratio of 0..497 was prepd. as above, pressed at 2500 bar, and sintered at 1800° for 20 h to give a product which had 81% transmission at a wavelength of 0.6m and 86% at 5m.

Hydrolizable organo-metallic compounds used for solidifying treatment of plasters and mortars

Hydrolizable organo-metallic compounds used for solidifying treatment of plasters and mortars. Ziegenbalg, Gabriele (Ziegenbalg, Gerald, Germany). Ger. DE 10327514 B3 20 Jan 2005, 5 pp. (German). (Germany). CODEN: GWXXAW. CLASS: ICM: C04B041-62. ICS: C04B041-64. APPLICATION: DE 2003-10327514 17 Jun 2003. DOCUMENT TYPE: Patent CA Section: 58 (Cement, Concrete, and Related Building Materials) The invention concerns a means to the rehabilitation of inorg. building materials such as plasters or mortar. It consists of (a) one or more organo-metallic compds., which hydrolyze one under formation or several alk.-earth metal hydroxides and (b) an org. solvent. The organo-metallic compds. 83329-04-8 and 15571-48-9 are just another two chemicals used in this study. are selected from methylate, ethylate, propylate, or isopropylate of magnesium, barium, and/or calcium. .
