Silicon Oxide( SiO2 ) Nanopowder General Description
A fine white powder composed of silicon oxide particles ranging from 10-30nm in diameter, this material is perhaps one of the most versatile and adjustable nanomaterials on the market. Also known as silica or silicon dioxide nanopowder, this material is primarily divided into two structure types, porous P-type silica and spherical S-type silica, which each lends itself to unique applications and properties.
Beyond this, silicon oxide nanoparticles can be further adapted through a number of surface modification processes. Over the years, researchers have discovered several worthwhile adjustments to be made to silica, leading to the widespread availability of variants modified to be hydrophobic and/or oleophilic, modifying them with epoxy or amino groups, treating the particles with coupling agents, etc.
Silicon Oxide( SiO2 ) Nanopowder Applications
Applications of these various forms of silica nanopowder are varied and encompass numerous industries and research avenues, including but not limited to:
Medical applications. Like many stable, non-toxic nanomaterials, silica nanoparticles have been extensively researched for their potential in specialized drug delivery systems. Silicon oxide nanopowders also play roles in more nanotech-specific, individualized therapies targeting specific diseases, in an approach combining therapeutic capabilities and diagnostic capabilities into a single agent called ‘theranostics’.
Composite materials. The high versatility of silica nanoparticles in their many configurations make them a key ingredient in the production of many different composite materials. The list includes, but isn’t limited to concretes, glasses, ceramics, alloys, plastics, and rubbers.
Paint. Silica nanoparticles have been extensively used in various paints to improve opacity and help add a smooth, glossy finish to the completed product.
Cosmetics. Like many non-toxic nanopowders, silicon oxide nanoparticles have been explored and applied extensively by the cosmetics industry in recent years. Silica, in general, has been used in cosmetics as an abrasive, a bulking agent, to render cosmetics more opaque, to prevent caking, and as a suspension agent.
Magnetics. The unique properties of certain formations of silica nanoparticles make them of value in producing a number of magnetic materials.
Catalyst. Like many nanoparticles, silicon oxide nanoparticles have been researched and applied extensively in catalysis. In particular, they’ve been used in various processes as both a highly effective catalyst carrier and a remarkably active catalyst.
