Ultra fine platinum powder is an important type of platinum powder with excellent physical and chemical properties, including oxidation resistance, corrosion resistance, and high conductivity. The shape and particle size range of ultrafine platinum powder are wide, which can meet different application needs. This article will provide a comprehensive introduction to ultrafine platinum powder, including its physical and chemical properties, preparation methods, application areas, and price.
1、 Ultra fine platinum powder has the following excellent properties:
High conductivity: Ultra fine platinum powder has better conductivity than traditional platinum powder because it can release a large amount of current in a shorter time.
High corrosion resistance: Ultra fine platinum powder has excellent corrosion resistance and can maintain good corrosion resistance in humid environments.
High definition: Ultra fine platinum powder has high definition and can be used in fields such as printing or metal coating.
Adjustable: Ultra fine platinum powder can be adjusted through different methods to meet different needs.
Affordable price: The price of ultrafine platinum powder is relatively affordable compared to traditional platinum powder, so it has been widely used in fields such as electronics, automobiles, and aviation.
2、 The preparation process of ultrafine platinum powder is relatively complex and requires multiple steps. Below is a brief introduction to several important steps:
The preparation of ultrafine platinum powder mainly includes three processes: metal dissolution, chemical reduction, and sintering.
Among them, dissolution is the basic preparation step, which separates metal ions through dissolution and then reduces them to powdered platinum atoms through chemical or physical reduction.
In the process of chemical reduction, gases such as hydrogen and ammonia are usually used as reducing agents to reduce metal ions to platinum atoms through high-temperature reactions.
After the reaction is completed, the product needs to be separated by crushing or sieving to obtain ultrafine platinum powder that meets the requirements.
During the separation and crushing process, attention should be paid to the selection of equipment and the control of operating environment to ensure that the quality of the produced ultrafine platinum powder meets the requirements.
In addition, the preparation of ultrafine platinum powder also requires attention to controlling parameters such as reaction temperature and pressure to ensure the stability and purity of the product.
When preparing ultrafine platinum powder, its quality can also be improved by adding additives and antioxidants.
3、 Ultra fine platinum powder has a wide range of applications in the field of catalysts:
It can serve as a catalyst for redox reactions, promoting reaction rate, reducing reaction temperature, and improving reaction selectivity. In addition, ultrafine platinum powder can also be used to prepare fuel cell electrodes, improving the energy density and service life of the battery.
In addition to being used in the fields of catalysts and electrodes, ultrafine platinum powder can also be used in the preparation of cosmetics. Due to its very small particle size and high surface area, ultrafine platinum powder can enhance the texture and touch of cosmetics, and has antioxidant, antibacterial, and anti-inflammatory effects.
Although ultrafine platinum powder has a wide range of applications in various fields, further research is needed on its preparation methods and applications. We can improve the performance and application range of ultrafine platinum powder through continuous research and innovation, and make greater contributions to social development.
4、 The purchase of ultrafine platinum powder should pay attention to the following points:
Specification and purity: When purchasing ultrafine platinum powder, pay attention to checking the product's specifications and purity to ensure that the purity meets the requirements.
Particle size: When purchasing ultrafine platinum powder, pay attention to the particle size to ensure that it is uniform and does not exceed the minimum particle size limit required.
Antioxidant properties: When purchasing ultrafine platinum powder, attention should be paid to the product's antioxidant properties to ensure that it does not lose its performance due to oxidation during storage and use.
Durability: When purchasing ultrafine platinum powder, attention should be paid to the durability of the product to ensure that it will not fail due to oxidation for a long time.
Adjustable: When purchasing ultrafine platinum powder, attention should be paid to the adjustability of the product to ensure that it can be adjusted as needed to meet different application needs.
Reasonable price: When purchasing ultrafine platinum powder, pay attention to the reasonable price of the product to ensure that it will not affect the cost-effectiveness of the product due to high prices.
After sales service: When purchasing ultrafine platinum powder, pay attention to the after-sales service of the product to ensure that any problems that arise during product use can be resolved in a timely manner.
By following the above precautions, it is possible to effectively prevent the purchase of unqualified ultrafine platinum powder, ensuring the quality and effectiveness of the product.
