Titanium Dioxide

Brand Name	Beiyuan		Place of Origin	China
Model Number	B102

1. Physical properties
In common white pigment, sharp titanium type the relative density of titanium dioxide minimum. Sharp titanium type under high temperature will transform into rutile type, so sharp titanium type of titanium dioxide melting point and boiling point is actually not exist. Sharp titanium type tio2 low dielectric constant, only 48. Sharp titanium type of titanium dioxide mok's hardness of 5.5 ~ 6.0, so in chemical fiber extinction to avoid wear silk spray holes and using sharp titanium type. Type A titanium dioxide whiteness is good, but only for R tinting 70% of the weather type, type in A  tio2 joined A year later after only specimens that began to crack or debris, and join R flaking occurs after specimens of titanium dioxide ten years after its appearance and only small change. Because R type titanium dioxide tinting strength and weathering resistance to better use  plastic shaded tio2.
2. Chemical properties
Sharp titanium type of titanium dioxide chemical properties extremely stable, is a partial acidic gender oxide. Under normal temperature barely and other elements and compounds reaction and oxygen, ammonia, hydrogen sulphide, carbon dioxide, nitrogen, and sulfur dioxide don't help, insoluble in water, fat, also insoluble in dilute acids and inorganic acid, alkali, only soluble in hydrofluoric acid. But in light effect, titanium dioxide can happen continuous REDOX reaction, have photochemical activity. This kind of photochemical activity, uv rays sharp titanium type of titanium dioxide particularly obvious, this nature made of titanium dioxide even some inorganic compounds photosensitive oxidizing catalyst, is certain organic compounds photosensitive reductive catalysts.
