Gold silver mixed slurry

Gold silver mixed slurryThe development process can be traced back to ancient times. As early as the Han Dynasty, China began using dense alloy materials containing metals such as gold, silver, and copper to make various exquisite objects and decorations. With the continuous advancement of modern technology, the research and application of gold silver mixed slurry have also developed rapidly.

At the beginning of the 20th century, a German chemist named Hans Goldschmidt first proposed the concept of metal powder welding, laying the foundation for later research on gold silver mixed slurries. Subsequently, people began to explore the preparation methods and properties of gold silver mixed slurries with different proportions. In 1937, a British engineer named John W. Arblaster first applied gold silver mixed paste to the field of electronics and successfully manufactured the first batch of gold silver mixed wires, pioneering the application of gold silver mixed paste in the field of electronics.

Below is a detailed introduction to the gold silver mixed slurry:

1. component

   
   

The gold silver mixed paste is mainly composed of gold and silver, and its ratio can be adjusted as needed. Normally, the gold content in the gold silver mixed slurry is between 60% and 80%, while the silver content is between 20% and 40%.

2. Preparation Method

There are two main methods for preparing gold silver mixed paste: physical mixing method and chemical reduction method.

(1) Physical mixing method: Mix gold and silver powders in a certain proportion, add an appropriate amount of solvent, and stir evenly to obtainGold silver mixed slurry.

(2) Chemical reduction method: Dissolve gold and silver salts in water, then add a reducing agent to reduce gold and silver ions into gold and silver particles, and then disperse them in water using surfactants to form a gold silver mixed slurry.

3. characteristic

(1) Color: The gold silver mixed paste has a very beautiful dual color of gold and silver, with warm and bright colors, making it very suitable for making jewelry.

(2) Conductivity: Gold silver mixed paste has good conductivity, so it is usually used to manufacture electronic components.

(3) Soft hardness: Gold silver mixed slurry has a certain soft hardness, which can be adjusted according to different manufacturing needs.

(4) Corrosion resistance: The gold silver mixed slurry is not easily oxidized at room temperature and also has good corrosion resistance.

4. application area

Gold silver mixed slurryWidely used in fields such as jewelry, electronic components, textiles, etc. The specific application scenarios are as follows:

(1) Jewelry: The beautiful appearance and high hardness of gold silver mixed paste make it one of the ideal materials for making jewelry.

(2) Electronic components: Due to the excellent conductivity of gold silver mixed paste, it is commonly used to manufacture electronic components such as connecting wires, capacitors, resistors, etc.

(3) Textiles: By spraying a mixture of gold and silver onto textiles, they can be endowed with special appearance effects, such as sequins, ribbons, etc.
