Recovery of silver palladium slurry_ Palladium containing waste recycling_ Precious metal recycling manufacturers

Silver palladium slurry is a special material composed of particles of silver and palladium, as well as other auxiliary components. It has good conductivity and thermal conductivity, so it is widely used in the electronics industry, catalyst preparation, and many other application fields. The preparation process of silver palladium slurry will be introduced in detail below.

The preparation of silver palladium slurry can be achieved through chemical or physical synthesis methods. Among them, chemical synthesis method is one of the most commonly used methods. The following is a common preparation process for silver palladium slurry:

1. Material preparation: Silver salt and palladium salt are key raw materials required for the preparation of silver palladium slurry. Common silver salts include Silver chloride (AgCl), Silver nitrate (AgNO3), etc., while common palladium salts include Palladium(II) chloride (PdCl2), Palladium(II) nitrate (Pd (NO3) 2), etc. In addition, it is necessary to choose appropriate solvents and surfactants to assist in the preparation process.

2. Solution preparation: Firstly, dissolve an appropriate amount of silver salt and palladium salt in different solvents, usually including water, alcohol solvents, etc. Then, mix the solutions of the two salts together and add an appropriate amount of surfactant. The function of surfactants is to help stabilize the dispersion state of silver palladium particles.

3. Addition of reducing agent: In order to reduce the salts of silver and palladium into metal particles, a reducing agent needs to be added. Commonly used reducing agents include ethylene glycol, formaldehyde, etc. The selection of reducing agents should be determined based on specific experimental conditions and requirements. After adding a reducing agent, the silver palladium ions in the solution will gradually be reduced to metal particles.

4. Mixing and stirring: Under the action of a reducing agent, the salts of silver and palladium gradually reduce to metal particles and form a slurry in the solution. In order to obtain a uniform silver palladium slurry, it is necessary to thoroughly mix and stir the solution. The stirring speed and time can be adjusted according to experimental requirements.

5. Filtering and washing: After mixing and stirring, filter the silver palladium slurry solution to remove solid particles. The filtered slurry can be washed to remove residual impurities and solvents. Washing can be carried out using appropriate solvents or solutions until a pure silver palladium slurry is obtained.

6. Drying: Finally, dry the washed silver palladium slurry to remove residual solvents. The drying methods can include natural air drying, vacuum drying, etc., depending on the preparation requirements and equipment conditions.
