Title: Separate-phase-natured aventurine glass and production thereof
Inventor: KOKUBU TOSHINORI
IPC: C03C4/02
Filed: 1988-07-28
Abstract: PURPOSE:To obtain the title delicate glass with unique color tone and pattern by forming an aventurine crystal phase in a separate-phase glass followed by secondary heat treatment to induce separate phase. CONSTITUTION:The objective glass can be obtained by the following process: a raw material mixture comprising (a) a basic glass composition comprising 30-60wt.% of silicic acid, 5-20wt.% of aluminum oxide, 5-25wt.% of boron oxide, 3-15wt.% of calcium oxide, 0.5-2.0wt.% of magnesium oxide and 1-10wt.% of alkali metal oxide, (b) an aventurine-forming agent comprising 0.005-0.02wt.% of gold, 0.2-1.0wt.% of chromium oxide 0-2.0wt.% of cadmium sulfide and 0-2.0wt.% of cerium oxide, and (c) as a molten atmosphere regulating agent 0.1-1.0wt.% of metallic magnesium, is melted at 1300-1500 deg.C followed by cooling to obtain a basic glass, which is then heated to 900-1100 deg.C and kept in this state to form crystals, thus obtaining an aventurine glass. This glass is then heated again at the separate-phase temperature of 700-800 deg.C to induce separate phase, thereby manifesting the color and pattern differing from those for the basic glass.

Title: Preliminary treatment for molten iron
Inventor: YAMADA SATORU
IPC: C21C1/02
Filed: 1981-11-24
Abstract: PURPOSE:To prevent rephosphorization after dephosphorization effectively and to improve the effect of dephosphorization markedly by charging molten iron into a vessel which is regulated of a ratio between height and an average diameter and is long longitudinally in a vertical direction and adding a dephosphorizing agent and an oxygen source. CONSTITUTION:Molten iron is charged into a vessel of H/D=2-5 (H; height, D; average diameter), and a dephosphorizing agent (e.g.; CaO) and an oxygen source (e.g.; scale having a controlled grain sizes) are added, whereby the molten  iron is dephosphorized. Since the above-mentioned vessel is longitudinally long  in a vertical direction, the time for moving (floating) the added dephosphorizing agent to the top part of the molten iron is long and the contact time with the molten iron is long; therefore, the effect of dephosphorization is improved. Since the dephosphorized flux of a high concn. is small in contact area with the molten iron, the rate of rephosphorization is small. Thus, the effect of dephosphorization of the molten iron is improved markedly.
