Product Overview
Low Sodium White Fused Alumina is a high-performance abrasive and refractory material manufactured from high-purity alumina through an electric arc furnace fusion process. By controlling the sodium content during production, this material offers improved purity and stability for applications where alkali impurities need to be minimized.
Compared with conventional white fused alumina, low-sodium grades are particularly suitable for precision grinding, ceramic manufacturing, refractory production, and other industrial applications requiring consistent chemical composition and reliable thermal performance.
Controlled low sodium content helps reduce alkali-related reactions and supports stable performance in high-temperature and precision manufacturing environments.
Xinli Abrasives supplies low-sodium white fused alumina in a range of grit sizes and micro-powder specifications. Particle size distribution, purity, and chemical composition can be adjusted according to application requirements.
The product is suitable for manufacturers of abrasive tools, polishing compounds, technical ceramics, refractory products, and precision surface treatment materials.
Abrasive manufacturing, ceramics, refractory materials, electronics, precision polishing, and industrial surface finishing.
