Introduction
1. Background of standard formulation and analysis of technological evolution
GB/T 7160—2017 National Standard for Carbonyl Nickel Powder is an important specification for nickel powder products produced by the carbonyl process. This standard replaces the previous GB/T 7160—2008, and is mainly revised in terms of brand classification, chemical composition requirements, physical performance indicators and testing methods.
With the advancement of carbonyl process technology and changes in market demand, the new version of the standard has put forward higher requirements for product quality control. In particular, the new test requirements for sieved particle size have been added, and the test index for specific surface area has been cancelled, reflecting the trend of technological development.
2. Comparative analysis of standard frameworks
| Standard version | Main revisions | Technical indicator changes | Applicable scope adjustment |
|---|---|---|---|
| GB/T 7160—2008 | - 8 grades are specified- Chemical composition requirements are relatively loose- Bulk density and Fisher particle size range are relatively wide | - Requirement for testing sieved particle size is deleted- New method for determining oxygen content | - Mainly applicable to nickel powder produced by carbonyl process |
| GB/T 7160—2017 | - Grades are reduced to 6- Standardization of brand designation method - Main uses are clearer | - New screening particle size detection requirements - Adjustment of chemical composition limits | - Expansion to more fields such as powder metallurgy and batteries |
3. Comparison of carbonyl nickel powder brands and properties
Table 1 and Table 2 list the chemical composition and physical property requirements of each brand in detail. The following is a comparative analysis of key indicators:
| Grade | Bulk density/(g/cm³) | Fisherman particle size/μm | Sieve particle size/μm | Application |
|---|---|---|---|---|
| FNiT04 | 0.30~0.50 | 1.2~1.8 | 180 | Catalyst, battery, etc. |
| FNiT06 | 0.50~0.65 | 2.1~2.8 | 180 | Batteries, powder metallurgy, etc. |
| FNiT09 | 0.75~1.00 | 2.0~3.0 | 180 | Powder metallurgy, etc. |
4. Implementation suggestions and application cases
Implementation suggestions:
- The supplier should strictly follow the standard requirements for production and establish a complete quality management system.
- The purchaser should clarify the product purpose and special requirements when purchasing to ensure that the supply and demand parties reach an agreement on quality indicators.
- It is recommended to conduct regular quality reviews and process optimization to improve product quality and consistency.
Application Case:
FNiT24 grade carbonyl nickel powder has outstanding performance in the field of powder metallurgy due to its high bulk density and large particle size. A battery manufacturer adopted FNiT06 grade products, which significantly improved battery performance and production efficiency.
