性の向上が図られているが、Ｗの酸化を防止する
に足る合金が発見されていないのが実情である。 Conventionally, containers made of W or W alloy have been widely used as crucibles for melting ores containing high-temperature glass and metal oxides, trays for vacuum deposition, boats, and the like. This is because W has a very high melting point of about 3400°C and has excellent mechanical properties at high temperatures. However,
When the temperature exceeds 500°C, W reacts with oxygen in the air to form an oxide, and this oxide easily evaporates, so it has to be used in an inert atmosphere, which is a hassle. Furthermore, even when used in such an inert atmosphere, when melting glass or ore containing metal oxides, oxygen and W contained in the melt combine to form oxides. The disadvantage was that the W in the container was eluted and the life of the container was short. For this reason, attempts have been made to improve wear resistance by adding other metals to the alloy, but the reality is that no alloy sufficient to prevent oxidation of W has been discovered.
本発明は上記欠点に鑑みなされたものであり、

Pt−Rh、Ir−Rh、がある。 In the present invention, Rh or a Rh alloy is used because Rh has a high melting point of 1966°C, which is similar to that of W, and although it combines with oxygen at temperatures above 600°C, it has a melting point of 1100°C.
This is because it decomposes and has excellent oxidation resistance, especially oxidation resistance against metal oxides. However, innocent
Containers made of Rh and Rh alloys are expensive and difficult to process, so we decided to coat them. For coating, physical vapor deposition such as ion plating, sputtering or vapor deposition is better than wet vapor deposition. According to physical vapor deposition, this is W
This is because the Rh atoms are buried in the surface layer of the container, increasing the adhesion strength of the bonding surface between Rh and W alloy, resulting in a clad container with high mechanical strength. In this way, a crucible coated with Rh or Rh alloy has excellent oxidation resistance and mechanical strength of the joint surface, so it has a long life. In addition, as a Rh alloy,
There are Pt-Rh and Ir-Rh.
以下、実施例と従来例について説明する。 Examples and conventional examples will be described below.

It was used at 1200°C for 60 minutes. When this process was repeated 10 times, 50μ of the conventional product was scraped from the surface of the W container, whereas 10μ was scraped for product 1 and 5μ for product 2.
It was only deleted.

The weight loss was 20g, whereas the weight loss of Example 2 was not.
