| According to a recent announcement by the China Standardization Committee for Materials and Testing (CSTM Standardization Committee), the standards "Ammonium Polyvanadate" and "Silicon Nitride Ferrovanadium " jointly drafted by PISI, Chengde Vanadium Titanium New Materials Co., Ltd., Hebei Iron and Steel Group Chengde Branch, and Panxi Vanadium and Titanium Inspection Institute have been successfully released.
Vanadium is a vital strategic resource, primarily used in the steel, chemical, aerospace, and new energy industries. The quality of ammonium polyvanadate directly affects the value of downstream vanadium products. Currently, the industry uses enterprise standards for production, lacking unified standard specifications and technology. Differences in product inspection and packaging can lead to disputes during transactions, hindering the healthy and orderly development of the industry. Therefore, it is urgent to formulate standards for ammonium polyvanadate to address the lack of consistency in technical indicators. The release of the "Ammonium Polyvanadate" standard is beneficial to improve the quality of ammonium polyvanadate products and the orderliness of transactions, enhancing the comprehensive utilization efficiency of vanadium-containing materials.
Silicon nitride ferrovanadium is a new alloying additive for steelmaking, that combines the high nitrogen content of silicon nitride and with the micro-alloying of vanadium nitride. So far, there has been no unified standard specification for the technical requirements, packaging, storage, labeling, and quality certification of silicon nitride ferrovanadium products in China. This standard provides a basis for the production and delivery of silicon nitride ferrovanadium products. It aims to regulate the transactions between parties, establish rules for market competition and promote the healthy development of the industry.
The release of the two standards has standardized the testing requirements for related products, including sampling and specimen preparation, chemical analysis methods for relevant elements, as well as the determination of bulk density and burn rate. |
