Active calcium, also known as activated calcium carbonate, possesses unique physicochemical properties. Here's a concise overview of its characteristics:
Appearance & Physical Properties: Active calcium appears as a white, odorless powder, non-flammable, stable in air but reactive with CO2 to form calcium carbonate. It has a low refractive index and is easy to color. After activation, its molecular structure changes, resulting in uniform particle size distribution and hydrophobicity.
Chemical Properties: Insoluble in water but soluble in acidic solutions, active calcium exhibits strong reducing properties, reacting with oxygen and water to release hydrogen and generate heat. It reacts vigorously with alkaline or acidic solutions.
Application Performance: Active calcium exhibits excellent dispersion and flowability, reducing viscous resistance between particles. It has significant lubricating effects, enhancing processing techniques and product performance. It also reinforces materials, improving tensile, compressive, and abrasion resistance. It can be used as a filler in rubber, plastics, and other materials, increasing fill levels and reducing costs.
Safety Precautions: Store active calcium in sealed containers away from moisture. Wear protective gloves and goggles when handling. Keep away from fire and flammable materials, and ensure adequate ventilation during use.
