The ZUMiR production facility in Kazakhstan specializes in sourcing and processing top-quality microspheres (cenospheres). Kazakh microspheres are characterized by a wide particle size range (20–500 μm), a light gray to nearly white color, and low density (0.4–0.8 g/cm³). They are produced as a by-product of coal combustion in power plants, with silica and alumina as their main components.

Key features of Kazakh microspheres:

• Low density and high mechanical strength
• High thermal resistance
• Excellent insulating properties and chemical inertness
• Wide application in the construction, chemical, automotive, and oil industries

The production process involves advanced stages of cleaning, drying, and fractionation, which ensures a product with consistent, high-quality parameters. Kazakh microspheres are delivered to customers in Europe and North America, where they are widely used as a lightweight, durable, and environmentally friendly raw material.
