OX0288 Micro Titanium Dioxide (TiO2) 500 μm Powder (CAS No. 1317-80-2)

Mikro-Titanoxid (TiO2) 500μm Powder Description

This titanium dioxide is produced in accordance with defined specifications. It is used in catalysis, in the production of paints, in transparent functional coatings, and in nanostructured layers for sensors and membranes.

Key Features and Advantages:

1. UV Protection: Micro titanium dioxide effectively blocks ultraviolet radiation. It is a principal component in sunscreens, thereby protecting the skin from harmful UV exposure.
2. Whiteness and Opacity: The product exhibits a consistent white colour and a high refractive index. Consequently, it is incorporated into pigments and paints to enhance opacity and brightness.
3. Photocatalytic Activity: Its photocatalytic properties enable the degradation of organic contaminants when exposed to light. Consequently, it is applied in environmental systems to purify air and water.
4. Antimicrobial Properties: Titanium dioxide nanoparticles demonstrate antimicrobial effects. They are therefore used in antibacterial coatings, paints, and medical products.
