In 2026, domestically produced high-purity calcium carbonate achieved a milestone breakthrough, truly breaking through in all aspects!

Who will be the first to break through?

Ningbo Songsheng New Material Technology Co., Ltd. is expected to officially commence production of its 20,000-ton annual electronic-grade ultra-high purity calcium carbonate production line in August 2026!

Ningbo Songsheng New Material Technology Co., Ltd., established on August 11, 2025, and owned by Ningbo Defeng Technology, is located in Ningbo, Zhejiang. It is a high-tech enterprise specializing in the research, development, production, and sales of high-end food additives and high-purity inorganic functional materials.

The company's core products cover food-grade and electronic-grade calcium powder, including ultra-high purity calcium-based powders such as food-grade calcium carbonate, light calcium carbonate, calcium hydroxide, and calcium oxide. We can customize 3N, 4N, and 5N high-purity powders according to customer needs, providing stable, self-controllable, and domestically produced supply chain support for downstream high-end fields such as electronic ceramics, new energy, and semiconductors.

The commissioning of Songsheng New Material's 20,000-ton annual electronic-grade ultra-high purity calcium carbonate project has made it the first enterprise in China to achieve large-scale production of 4N-grade (purity > 99.99%) calcium carbonate, breaking the long-term overseas monopoly in one fell swoop.
