Recently, the electronic-grade phosphoric acid plant of Wengfu Zijin, a subsidiary of China GPC, successfully completed the one-time chemical feeding test run. All product indicators are superior to the G1 grade of the General Standard for Wet Electronic Chemicals, and some key indicators have reached the G3 grade, placing it at an advanced level in the industry.

During the test run, the special test run team efficiently coordinated resources, overcame multiple technical bottlenecks and operational challenges, quickly responded to various emergent situations, optimized process parameters, and ensured the rapid response and efficient implementation of instructions, laying a solid foundation for the successful one-time test run.

As a key basic material for electronic information industries such as integrated circuits, flat-panel displays, and solar cells, the purity and stability of electronic-grade phosphoric acid are directly related to the performance and yield of downstream products. Currently, the domestic high-end electronic-grade phosphoric acid market has long relied on imports. Wengfu Zijin's technological breakthrough this time not only improves the independent supply capacity of domestic electronic chemicals but also provides a guarantee for the security of relevant industrial and supply chains.

In the next step, the project team will systematically summarize the test run experience, formulate a special rectification plan, promote the plant performance assessment and continuous stable operation, and accelerate the realization of large-scale mass production. This successful test run has laid a solid foundation for Wengfu Zijin to expand the high-end electronic chemicals market and further enhanced the enterprise's competitiveness in the global fine chemical field.
