• Neutralizer/alkalinity control (water, flue gas
desulfurization). • Rubber & plastics filler, flame retardancy synergy (with ATH/MDH). • Agriculture (feed & soil Mg source), sugar refining, ceramics & glass. • Refractory bricks (DBM), cement & construction. |
• 25 kg PP bags with liner • 500–1000 kg FIBCs • Bulk. | • Hygroscopic; store dry and sealed. Avoid acid contact; reacts to form salts and heat. Use dust control and PPE; review SDS before handling. |
Specs are representative; we tune fineness, reactivity and
impurity profile per application (feed, rubber, environmental,
refractory). Samples available.
