1. Technological breakthroughs across the board: From raw material adaptability, synthesis processes, product specifications to downstream application adaptability, achieving full autonomy and controllability across the entire chain, thoroughly solving the "bottleneck" problem of domestic high-end powder materials.
· No specific raw material requirements, low-cost mass production
· Dual controllability of particle size and impurities
· Customized coverage across multiple levels, including 3N/4N/5N
2. Breakthrough in production capacity: Domestic high-purity calcium carbonate has long remained at a small-scale production capacity of 3N grade, with a production capacity of thousands of tons, which cannot meet the batch production needs of high-end manufacturing.
Songsheng New Materials has directly increased its production capacity to 4N grade, achieving a production scale of 10,000 tons per year. This makes it the largest and highest-grade electronic-grade calcium carbonate production line publicly reported in China.
Globally, only a few Japanese companies and Songsheng New Materials possess large-scale supply capabilities, marking the official entry of domestically produced ultra-high purity calcium carbonate into the global top tier.
3. Breaking through in the market. Currently, Songsheng New Materials' 4N/5N high-purity calcium carbonate has been sent to domestic leading electronic ceramic, chip packaging, and new energy enterprises for sample verification, and the feedback has been positive.
In the future, the enterprise will also expand into overseas high-end markets such as South Korea and Japan, participating in global competition with domestically produced high-quality products.
The significance of comprehensive breakthrough: reconstructing the pattern of high-end calcium-based materials 1. Solving the development dilemma of the domestic calcium carbonate industry · Food-grade and pharmaceutical-grade calcium carbonate (purity 98.5%–99%): limited by raw ore and supply chain, upgrading is difficult
· Ordinary industrial-grade calcium carbonate (≤98.5%): trapped in high investment, high energy consumption, low profits, and price competition
Songsheng New Materials has leveraged technological innovation to break away from the cycle of competition and promote the industry's transformation towards high purity, high added value, and high-end applications.
2. Supporting the national high-end manufacturing of self-controlled 4N grade ultra-high purity calcium carbonate, which can be widely applied in: chip packaging, electronic ceramics, optical lenses, aerospace, 5G communication, new energy materials, chemical testing, and life sciences
As a key basic material, its domestic substitution directly ensures the security of the high-end manufacturing supply chain, injecting "material confidence" into China's high-tech industry.
The domestic substitution of key basic materials is the core support for the autonomy and controllability of high-end manufacturing.
The comprehensive breakthrough of domestically produced 99.99% high-purity calcium carbonate is not only a milestone for Ningbo Songsheng New Materials, but also an important symbol of the high-end and domestic production of inorganic functional materials in China.
From purity breakthroughs, controllable particle size, to the implementation of ten-thousand-ton production capacity, China's high-end calcium-based materials are emerging with a new posture, supporting the steady and long-term development of China's high-end manufacturing industry.
