Microsilica, also known as silica fume, is a highly reactive pozzolanic material produced as a byproduct of silicon metal and ferrosilicon alloy smelting. With SiO2 content typically exceeding 85-98%, it is widely used as a concrete additive to improve compressive strength, durability, and chemical resistance, and as a critical raw material in refractory linings and specialty ceramics. For international buyers sourcing microsilica for construction materials or industrial applications, understanding bulk density, moisture content, and loss on ignition (LOI) specifications is essential for quality assessment and import compliance.
