High Purity and High Activity for Precision Applications
We offer Composite Alkali Powder. This product reflects our pursuit of "high purity" and "high activity." We use high-grade limestone as the raw material. It is processed through high-temperature calcination, fine grinding, strict screening, and composite modification.
Our factory was established in 2017 and has extensive experience in producing calcium-based products. Our team consists of 30 skilled employees, including more than 12 technical staff. We are not just a supplier-we are a trusted expert in alkaline raw materials. Our Composite Alkali Powder is a premium-grade product.
Key Specifications and Superior Quality
We maintain strict quality control throughout the entire production process, ensuring stable chemical composition and excellent physical properties. The table below presents our high-purity product range.
CA-95-200 is a high-purity economic grade with strong alkalinity, suitable for high-concentration acid neutralization and high-standard environmental engineering applications.
CA-95-325 is a high-purity ultra-fine grade with extremely fast reaction speed, designed for precision chemicals, pharmaceutical intermediates, and high-end water treatment applications.
Our Composite Alkali Powder is designed for demanding industrial uses.
