integrity

We fulfill our commitment through rigorous quality control of electronic-grade ultra-high purity materials, establishing a transparent cooperation system that ensures full traceability from raw material synthesis to finished product delivery, safeguarding the long-term trust between our customers and industry chain partners.

innovation

With R&D investment accounting for over 20% of revenue, we have overcome technical challenges for 10 years, with an average of 0.3 new patents added daily. We have tackled core process bottlenecks such as high purification, nanocrystallization, and low impurity levels, breaking the international monopoly of 4N-grade electronic-grade calcium carbonate.

development

With an annual production capacity increase of 35%, we have achieved a strategic transition from being reliant on imports to becoming a global standard-setter through our dual-track layout of research and development and manufacturing.
