Development of porcelain for lower firing temperatures

Development of porcelain for lower firing temperatures. Imai, Kanzi; Isomatsu, Yoshizumi; Asami, Kaoru (Kyoto Munic. Inst. Ind. Res., Kyoto 601, Japan). Yogyo Kyokaishi, 92(1), 42-9 (Japanese) 1984. CODEN: YGKSA4. ISSN: 0372-7718. DOCUMENT TYPE: Journal CA Section: 57 (Ceramics) A large amt. of thermal energy is required for the firing of porcelain ware which is generally carried out at as high as 1300°. To minimize energy required in the firing of porcelain, a new compn. which can be fired at 1100° without losing its porcelain properties was developed, and its characteristics, such as vitrification, were investigated. The compn. of the body was 0.40 KNaO, 0.16 CaO, 0.21 MgO, 1.00 Al2O3, 6.99 SiO2 0.10 B2O3 by the Seger formula. Although the body contained B2O3-frit and alkali and alk. earth metals as additives, a stable vitrification of the body was maintained, and no difference could be obsd. in the mineral compn. and phys. characteristics of the porcelain prepd. from the body and the typical vitrified porcelains prepd. by the conventional method. The green body is based upon pottery stone (Toseki) which possesses plasticity, therefore, no modification of the conventional process is necessary for molding. 1305-78-8 and 1313-59-3 which are cas registry numbers of substances are two of reagents here. Decreases in firing time of ~30% and in fuel consumption of 30-40% were obtained in an exptl. kiln. (internal vol. ~0.53 m) compared with the firing of a body contg. no additives. .

EPMA study of fast sodium ion transport

EPMA study of fast sodium ion transport.Some chemicals with cas registry numbers like 77641-62-4 and 1313-59-3 are also used. Kuo, Chukun; Li, Shantin (Shanghai Inst. Ceram., Chin. Acad. Sci., Shanghai, Peop. Rep. China). Solid State Ionics, 9-10(Pt. 1), 177-80 (English) 1983. CODEN: SSIOD3. ISSN: 0167-2738. DOCUMENT TYPE: Journal CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) Section cross-reference(s): 57 Electron-probe microanal. (EPMA) expts. were performed on Na ion conductors including b- and b''-aluminas, Nasicon, and high-conductive glass. Based on the mechanism of ion transport in a const. elec. field with a source of diminished carrier concn., a kinetic equation for Na accumulation was derived, by which the increase of Na counts with time during electron injection can be followed and reasonably well fitted. Morphol. observation of the Na distribution on single and polycrystals after electron bombardment reveals the relations between the Na ion transport characteristics and the crystal orientation or the microstructures. .
