Abstract

The invention relates to a multicomponent alloy catalytic agent used for compounding diamond. The alloy comprises the following components: 25-30% of nickel, 0.5-2% of tungsten, 0.5-1.5% of titanium, 0.5-2% of carbon and the balance of iron. The invention further relates to a preparation method for the multicomponent alloy catalytic agent and an application thereof to the compounding of diamond. The multicomponent alloy catalytic agent provided by the invention takes iron, nickel, tungsten, titanium and carbon as raw materials at specific ratio, and the excellent properties of uniform component and low impurity content, such as, oxygen, silicon, sulfur, phosphorus, and the like of the multicomponent alloy catalytic agent can be ensured. The multicomponent alloy catalytic agent is prepared by preferably adopting a water atomization method and has the performances of low manufacturing cost, high yield, and the like. The multicomponent alloy catalytic agent provided by the invention can be used for preparing high-class artificial diamond with high yield, strong cold / heat impact toughness and low magnetic susceptibility.

Description

technical field

[0001] The invention relates to the field of diamond synthesis, in particular to a catalyst material for synthesizing high-grade diamond. Background technique

[0002] Synthetic diamond has extremely high hardness and good thermal, optical, and electrical properties, and plays a great role in the fields of stone, construction, engineering ceramics, automobiles, aviation, and aerospace. After more than 50 years of development in my country, synthetic diamond has formed a complete and huge emerging industrial system. Catalyst is a substance that realizes the mass production of synthetic diamonds by greatly reducing the temperature and pressure required for synthetic diamonds during the synthesis of synthetic diamonds. The catalyst material of synthetic synthetic diamond directly determines the grade of synthetic synthetic diamond, and is the core raw material of synthetic synthetic diamond.
