Definitions

  • a ceramic composition which is for example quartz general showed a greater expansion by transformation in the firing Atsushi Nobori process, if it exceeds 570 to 60 0 ° C the thermally expanded is 8 0 X 1 0 - becomes more than Te 7 Bruno , whereas, in the temperature below 600, RiNoboru thermally expanded by including the contraction of the clay component Ri dirt floor and the 5 0 ⁇ 6 0 X 1 0 7 Z ° C as low level, 1 000 ° C At the above sintering temperature, large sintering shrinkage of 5 to 10% is exhibited. Therefore, in the case of the conventional general ceramic composition, as shown in was example, if FIG.
  • a preferred ceramic composition for realizing a ceramic sintered body having a metal as a skeleton of the present invention is (CaO + Mg0 + A123) / Si02.

  • These metallic materials generally have a greater degree of thermal expansion than the above-mentioned composition, but in order to absorb this difference, an organic paste such as starch, polybutyl alcohol, or M.C. It is also effective to provide a coating of the material.
  • This organic glue material does not easily disappear when the oxygen content in the composition is low, and begins to carbonize at about 350 ° C. Even at 1200 ° C, the surface layer of the rebar as carbon is formed. To be retained. As long as this carbon remains, oxidation of the rebar does not proceed easily.When firing is completed, the incision is made and the state of the rebar surface is observed. Indicates a certain state.
  • the thickness of the organic glue layer may be 0.5% of the rebar diameter according to the results of the experiment, but considering the amount of residual carbon remaining on the surface layer and the absorption of stress due to the longitudinal expansion and contraction of the rebar, the diameter is It is desirable to set it to 1.0% or more. If the thickness of the coating film is required to be 0.05 mm or more, it is effective to mix charcoal powder and paper powder.
  • Starch and charcoal powder were mixed at a weight ratio of 1: 1. After adding 10 to 12 times the amount of water and heating to adjust the glue, it was applied to the rebar surface to a film thickness of about 0.2 mm and dried. .

Abstract

Corps céramique fritté dans lequel un matériau métallique linéaire, en forme de baguette ou à mailles est entièrement noyé selon une disposition d'ossature prédéterminée. L'invention se rapporte à un corps céramique fritté dans lequel une ossature métallique comprenant des barres de renforcement ou autres est entièrement noyée, un tel noyage de l'ossature métallique étant considéré comme impossible à réaliser selon les techniques classiques. On obtient ainsi un matériau de construction d'une fiabilité supérieure du point de vue de la robustesse, la céramique présentant également une résistance supérieure par rapport aux conditions atmosphériques.
