Embodiment 1

[0014] Add 580 grams of 40-mesh zinc powder and 130 grams of copper citrate powder into the reactor with a stirring device, fully replace the air in the reactor with nitrogen, and heat the reactor to 450°C while stirring Carry out carbonization under low temperature, react for 1 hour to complete the reaction, cool to room temperature, and obtain a new type of copper-zinc alloy powder. The heating method is electric heating. The alloy powder is used for preparing diethyl zinc, and has the characteristics of fast initiation speed, high yield, high purity and stable reaction process.

Embodiment 2

[0016] Add 1040 grams of 80-mesh zinc powder and 200 grams of copper citrate powder into the reactor with a stirring device, pass argon gas into the reactor, fully replace the air in the reactor, and while stirring, electric heating reaction The temperature of the kettle was raised to 100° C. for carbonization, and the reaction was completed after 3 hours of reaction, and cooled to room temperature to obtain a new type of copper-zinc alloy powder. The alloy powder is used for preparing diethyl zinc, and has the characteristics of fast initiation speed, high yield, high purity and stable reaction process.

Abstract

The invention relates the method for preparation of copper-zinc alloy powder, comprising the following steps: adding the 80-90wt% zinc powder and 10- 20% copper citrate powder into autoclave with agitator, entering agitator, heating to 100-450Deg.C, carrying out carbonation for 1-3 hours, cooling , and getting the copper-zinc alloy powder. The cost is low. Using the method, the product possesses the high activity.

Description

technical field [0001] The invention relates to a method for preparing an alloy, in particular to a method for preparing a novel copper-zinc alloy powder. Background technique [0002] Diethyl zinc is one of the most important catalyst monomers used in the research and production of carbon dioxide-based fully degradable plastic resins. At the same time, diethyl zinc is also an MO source for MOCVD, an important growth method for compound semiconductor thin film materials. It is an important dopant for materials such as gallium, and can also be used to prepare materials such as ZnSe and ZnS. In the MOCVD process, the purity requirement of diethyl zinc is very high. If it contains a lot of impurities, it will directly affect the photoelectric performance of the prepared material. [0003] However, the production cost of diethyl zinc produced at home and abroad is very high at present, and the main factor affecting the cost of diethyl zinc includes the cost of copper-zinc alloy...
