Abstract: PROBLEM TO BE SOLVED: To obtain a β-spodumene structure and further to provide a method for preparing the β-spodumene structure. SOLUTION: This method for preparing a β-spodumene structure comprises preparing a homogeneous plastic batch comprising an inorganic raw material, an organic binder and a vehicle, in which the inorganic raw material comprises about 75-95 wt.% mineral and about 5-25 wt.% glass. A green ware is formed out of the batch, and the green ware is fired to provide a structure substantially constituted of the β-spodumene, and having (0-800 deg.C) thermal expansion and >=4 Ksi strength.

Abstract: PROBLEM TO BE SOLVED: To specify a design parameter of an extruded ceramic honeycomb body constituting a catalytic converter to thereby improve the performance thereof. SOLUTION: An extruded ceramic honeycomb body having an entrance side, an exit side and a plurality of parallel open-ended passages formed by intercrossing cell walls crossing the honeycomb body from the entrance side to the exit side. The passage has a rectangular cross-section having at least a rectangular, aspect ratio of about 1.2:1, and an effective surfacial area coefficient Nμ/Dh of at least about 70 in relation to the honeycomb is regulated by the hydraulic pressure diameter Dh and isothermic Nusselt number Nμ of the rectangular passage.

Abstract: The mfr. of a low expansion lithium aluminosilicate honeycomb body comprises (i) compounding lithium aluminosilicate glass powder and a clay additive; (ii) extruding the batch through a honeycomb die; and (iii) drying and firing to produce a low expansion body which has a thermal expansion coefft. of below 15 x 10-7/[deg]C between room temp. and 800[deg]C, and a principal crystal phase composed of beta-spondumene solid soln. The clay additive is aluminosilicate clay as 2-30 wt.% of the solids of the batch or is kaolinitic clay as 5-20 wt.% of the solids. The compsn. of the glass powder is (wt.%) 4.9-7.1 Li2O, 6.5-22 Al2O3, 72-86 SiO2 and 0-2 TiO2; the solids of the batch have the compsn. 3.5-7.5 Li2O, 15-30 Al2O3, 65-85 SiO2 and 0-3 TiO2, and the Al2O3:Li2O mole ratio is 1-1.5. The firing temp. of the body is at least sufficient to crystallise the clay and powdered glass.

Abstract: A molten metal filter is disclosed having a carbon or carbon-thermite coating that reduces thermal shock to the filter, and protects the filter from corrosion from the metal or components and impurities in the metal, and prevents metal from freezing in the filter. A molten metal assembly suitable for casting molten metal is disclosed which comprises a filter for molten metal and means for molten metal flow passage leading through the filter. The means have surfaces defining a molten metal path. The filter has a coating of carbon or carbon in intimate contact with a thermite material on the surfaces of the filter. A process is disclosed for filtering molten metal which comprises passing molten metal through the above described coated filter.
