    摘要: An improved apparatus for preparation of high-melting-point high-toughness metals comprising a reaction chamber in which a halide of said metal is reacted with an active metal and the remaining active metal and the produced active metal halide are vaporized and a condensation chamber in which vapors of the remaining active metal and the active metal halide are condensed is disclosed. The apparatus comprises a reaction chamber and a condensation chamber as described above both of which are provided with a neck having a passage-closing means of the seal pot structure, and the two chambers are placed in parallel in the upright position and are connected with a horizontal connecting duct.

    摘要: A refractory is disclosed which contains integrally sintered magnesia particles forming the skeleton of the refractory and a mineral phase of magnesium orthotitanate (Mg.sub.2 TiO.sub.4) formed between the magnesia particles, thus giving an increased erosion resistance. Preferably, the refractory comprises coarse magnesia particles having an average particle diameter of at least 1 mm or a mixture of coarse magnesia particles having an average particle diameter of at least 1 mm and medium magnesia particles having an average particle diameter of 1 to 0.15 mm and 5 to 50 wt. % of magnesium orthotitanate intervening between the magnesia particles. The refractory not only has an excellent durability in a basic atmosphere, but also has a high strength because of combination of the coarse or medium magnesia particles so that it does not tend to deform and has a high durability against thermal shock.
