inertgranar

Inertgranar are small, chemically inactive solid particles used as non-reactive media in industrial and laboratory settings. They provide bulk, porosity, and mechanical stability without participating in chemical reactions, making them suitable as catalyst supports, fillers, calibration standards, and carriers in various processes.

Materials and forms include silica, glass, alumina, zirconia, calcium carbonate, and inert polymers. They are produced as uniform spherical beads or irregular granules, with particle sizes ranging from tens of micrometers to several millimeters. Surface treatments and pore structures can be tailored to enhance compatibility with specific applications.

Production and properties involve methods such as beadization, spray drying, extrusion, and polymerization. Key properties include chemical inertness, mechanical strength, thermal stability, density, porosity, and surface area. For applications in chromatography or catalysis, size uniformity and surface characteristics are especially important.

Applications span chemical engineering, chromatography, pharmaceuticals, and materials science. In chemical reactors and packed-bed columns, inertgran serve as catalyst supports and separation media. In analytical contexts, they provide non-reactive supports or calibration standards. In formulations and composites, inert carriers or fillers help control texture, density, and processing behavior.

Safety and regulation considerations are generally modest due to chemical inertness, but inhalation of fine powders can pose respiratory risks, so appropriate handling and dust control are advised. Disposal should follow local regulations for inert solids, with attention to any manufacturing residues. Environmental impact is typically low, reflecting their non-reactive nature.
