  • the present invention relates to a decorative article having an oxide film formed on a silicon surface having a flat surface.
  • the present invention provides a material having excellent decorativeness by coloring the silicon surface without using a coloring agent. Therefore, a single-layer oxide film is formed on the surface of the silicon having a flat surface. It is characterized by the fact that it has been formed.If a part of this oxide film is removed, or if polycrystalline silicon is used, precious stones with beautiful value such as radiance and color are obtained.

  • the uniform oxide film formed on the silicon plane changes its effective film thickness as shown in Fig. 7 depending on the viewing direction. Therefore, the color due to the difference in the film thickness described in the above-mentioned literature changes in various directions depending on the viewing direction, and even if it is a flat surface, it has a beautiful and highly decorative appearance. It is likely to be. In particular, it is thought that the cut surfaces are very beautiful because the color tone from each surface is different and changes gradually according to the viewing direction.

  • the thickness of the silicon oxide film according to each of the above embodiments is uniform, since the surface is a plate surface, the effective film thickness differs depending on the viewing angle, and the color of the reflected light differs. come. This is because when the light is reflected back in the oxide film, as viewed obliquely, the state becomes the same as the thickness of the oxide film increases.
  • the substrate is formed in a polyhedral shape, even if the oxide film has a uniform thickness, the surface / film thickness of each surface is different, so that the oxide film shines in various colors. Of course, if you look at each surface at right angles, it will look like the original color.

  • the silicon decorative article of the present invention has a beautiful appearance due to the thin oxide film on its surface, and in particular, those having a mirror-finished surface are slightly natural in the South Sea. It has an appearance similar to or better than the available black pearls. If these ornaments are offered in various shapes at low cost, the desire of the world for beauty can be fulfilled again. For men, silicone ornaments with colored rafts, durability, novelty, and applicability, such as neck pins and fues, are available. provide.
  • the thickness of the oxide film can be freely controlled by appropriately selecting the oxidation conditions, so that a silicon decorative article having a desired brightness can be manufactured with good reproducibility.
  • the silicon oxide film is the same as that of so-called quartz, it has high hardness, excellent chemical resistance and heat resistance, and can be made of natural pearl or any other material. More durable than such imitations.
  • the pearl absorbs sweat and deteriorates, but the silicone decorative article according to the present invention is stable.
  • the specific gravity is about 2.9 for pearls and about 2.3 for silicones, so they do not feel heavy when worn.
  • the silicon oxide film is inactive, it has no adverse effect on the human body, such as a metal alloy, which has recently become a problem.
  • the present invention utilizes the light interference effect of the silicon oxide film, the same effect can be expected by the nitride film. Since the nitride film has a higher hardness and is more stable than the oxide film, it can be used especially as a protective film.
  • the present invention is characterized in that an oxide film is uniformly grown on the surface of a silicon having a flat surface, or that the oxide film is partially etched.

Abstract

Matière brute à qualité décorative élevée, réalisée en formant des colorations sur une surface de silicium sans utiliser de colorants. Une couche unique d'un film d'oxyde est réalisée sur une surface de silicium plane. Après enlèvement d'une partie de ce film d'oxyde ou après application de silicium polycristallin, on obtient une pierre précieuse présentant un brillant et des colorations très esthétiques.
