能を有する合金の開発が強く要望されている。Conventional technology When manufacturing dental prostheses in dentistry, various alloys are used, such as gold alloys, gold-silver-palladium alloys, and silver alloys. is the most prized.
However, dental alloys need to be less expensive than precious metals and other alloys. Therefore, since gold is expensive, there is a strong demand for the development of an alloy that does not contain gold at all, or even if it does contain a small amount, that has excellent performance comparable to gold alloys.

る。 Conventionally, gold, silver, copper, and palladium have been used as base alloys, and platinum, indium, and zinc have been added to these alloys to adjust corrosion resistance, mechanical strength, and melting temperature. However, while copper is added to improve mechanical strength and castability, the addition of copper impairs the discoloration and corrosion resistance of the alloy in the oral cavity, and it also impairs the ability of the alloy to be cast immediately after casting. The cast surface of the body is covered with a black or black-gray oxide film. This black oxide coating is undesirable from the viewpoint of adhesion to the abutment and aesthetics when this alloy is used for crown restoration. In order to improve this drawback, a patent application filed in 1970-

つ加えて製造することができる。 The method for producing boron-copper is to first melt boron at a temperature of approximately 3000°C by discharging it between tungsten electrodes in an argon arc (with almost no oxygen) atmosphere, and then put copper in this and melt it. Although it can be produced, it contains a small amount of copper oxide due to melting at high temperatures, making the conditions for producing a pure boron-copper alloy difficult. Therefore, boron-copper was produced by the following method. It was produced by discharging between tungsten electrodes in an argon arc atmosphere, melting the copper, and adding calcium boride (CaB 6 ) or magnesium boride little by little to the melted copper. be able to.

Palladium is added to increase the hardness without reducing the sulfidation resistance and toughness of the alloy. If it is less than 5%, there is no increase in hardness, and if it is less than 10%, there is a significant decrease in toughness in spite of the increase in hardness. . 20 to 50% silver is in a range that improves the processability of the alloy. Indium is added to improve the sulfidation resistance and mechanical properties of the alloy. If it is less than 10%, no effect will be observed, and if it is more than 26%, the strength of the alloy will decrease. Zinc was added in the required amount as a deoxidizing agent.
