Amorphous refractory

Amorphous refractory. Taniguchi, Taizo; Iwasaki, Itsutoshi; Takeshige, Toshihiko; Onizuka, Koji; Hashiguchi, Soichi (Taiko Refractories Co., Ltd., Japan). Ger. Offen. DE 2744486 1 Jun 1978, 14 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C04B035-66. PRIORITY: JP 76-142509 26 Nov 1976. DOCUMENT TYPE: Patent CA Section: 57 (Ceramics) A refractory castable mixt. contains fireclay 3-12, Al powder (390%Al) 0.1-5, reaction inhibitor (i.e. gelatin, gum arabic, and citric acid) for Al 30.5, deflocculant (i.e. Na humate, Na silicate, and Na oxalate) 0.01-1.0, setting time accelerator (i.e. Ca(OH)2, CaF2, and CaCrO4) 1-8 wt.%, and a granular refractory (clay, bauxite, Al2O3, periclase, etc.). Water is added and the mixt. is cast. The forms are removed in 2-8 h and 60-70% water is vaporized at 100° in 3-8 h owing to heat from the reaction of Al with water. The casting is cured at 500-800°. Thus, a mixt. of granular grog 70, pulverized Al2O3 10, fireclay 10, Al 2.0, Na humate 0.2, Ca aluminate [11104-48-6] accelerator, and NH4 borate [11128-98-6] reaction inhibitor 0.1 wt. parts was cast with 10.0 wt.% water. Transverse strengths were 18, 20, and 28 kg/cm2 after 24 h aging, 110° drying, and firing at 1000°, resp. No cracks occurred during 144 10 min cycles between room temp. and 800°.

Solid electrolytic capacitor

Solid electrolytic capacitor. (New Nippon Electric Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58190016 A2 5 Nov 1983 Showa, 6 pp. (Japanese). (Japan).Several reagents with their cas registry numbers 11128-98-6 and 7440-25-7 are used here. CODEN: JKXXAF. CLASS: IC: H01G009-05; H01G009-04. APPLICATION: JP 82-74342 28 Apr 1982. DOCUMENT TYPE: Patent CA Section: 76 (Electric Phenomena) The fabrication of a solid electrolytic capacitor involves the following steps: (1) anodizing a valve-metal-compact capacitor element in a basic soln. at pH 38 to form an oxide layer having a surface-layer portion thicker than the deep-layer portion; and (2) anodizing the capacitor element in an acidic soln. to form an oxide layer thicker than the deep-layer portion and thinner than the surface-layer portion at the deep-layer portion. Thus, a Ta capacitor element was anodized in an ammonium borate soln. and then in a H3PO4 soln. The capacitor prepd. had a small leakage current. .
