Shaped, preferably porous, inorganic bodies are provided which are prepared from a reactive blend. In accordance with one preferred embodiment, the solution is absorbed into a porous sacrificial substrate such as a cellulose sponge. The solution-saturated substrate is heated and an oxidation-reduction reaction occurs thereby forming an inorganic solid. A shaped, inorganic body is formed in situ. Optional, but preferred additional thermal treatment of the shaped, inorganic body removes the organic substrate, leaving an inorganic body that faithfully mimics the porosity, shape, and other physical characteristics of the organic substrate. Inorganic substrates may also be used to good effect. Large varieties of shaped bodies can be prepared in accordance with other embodiments of the invention and such shapes find wide use in surgery, laboratory and industrial processes and otherwise. The invention also provides chemically and morphologically uniform powders, including those having uniformly small sizes. |

A passive insulating system can provide highly effective protection in the presence of transient high temperatures. The system comprises, for example, a porous body forming a multiplicity of fine cells with a material having low thermal conductivity, a thermally absorptive liquid, providing an endothermic reaction in the presence of a catalyst, and a finely divided catalyst for the reaction uniformly distributed in the porous body. In preferred systems, the thermally absorptive liquid is para-hydrogen, the catalyst is granulated ferric oxide, and the liquid para-hydrogen changes to gaseous para-hydrogen, and from para-hydrogen to ortho-hydrogen in the presence of the ferric oxide catalyst, absorbing heat by its heat of vaporization and endothermic catalytic reaction and reducing heat transfer through the porous body. |

A colored frit prepared by fusing by heating a material composition comprising a devitrifying substance, a coloring agent and glass, and a method for manufacturing an artificial stone made by utilizing the colored frit. In the method of manufacturing artificial stones, the colored frits alone or a mixture of at least one kind of the colored frits and at least one kind of the colored frits and at least one kind of frits containing fluormicas are sintered, so that the colored frits are devitrified and the colors of the devitrified colored frits become distinctly visible to a viewer. This produces artificial stones having a wide variety of distinct colors and patterns. |

A method of, and apparatus for, making a synthetic breakwater involves the steps of arranging flat, approximately parallel electrodes (20 and 22) which are approximately coextensive with one another, so that they are spaced from one another by electrically insulative materials (10) with a gap of from 3 cm to 27 cm. An electrical potential is applied across these electrodes to cause a current density flowing between the electrodes of not greater than 0.1 milliamps (ma) per cm.sup.2. In the preferred embodiment, the electrodes are spaced approximately 5 cm apart and a voltage of around 3 volts is applied thereacross. The flat cathode is of expanded electrically-conductive metal, with the anode being constructed of two materials, one of them being an outer casing (30) of lead. |

PURPOSE: To prepare artificial stone having various colors and various patterns by prepg. colored frit from molten raw material compsn. comprising devitrifying material, coloring material, and glass, and sintering the colored frit.
CONSTITUTION: Each devitrifying material component, coloring material component, and glass component is mixed with each other in the powdery state uniformly, and the mixture is melted completely in a heating furnace at ca. 1,300W1,500°C. Then, the molten body is quenched under supercooling condition causing no crystallization of the devitrifying material such as by flowing down in water stream. The cooled mass is crushed regulating the particle size to ca. 0.5W5.0mm particle size. The colored frit prepd. by the above described method is packed in a refractory shell plate in accordance with a specified design, and molded. After heating the molded body charged to a heating furnace to room temp. Wca. 400°C at 150W200°C/hr, it is further heated to ca. 600°C at 50W80°C/hr. Then, the heated product is held at near the softening temp. of the compound material for ca. 1W2hr, it is allowed to cool by standing to prepare the sintered body of the product.
