Titanium Dio Ide Electroluminescent

TITANIUM DIOXIDE

Titanium dioxide is produced by either the sulfate or the chloride process. Processing conditions determine the form (anatase or rutile structure) of the final product. In the sulfate process, sulfuric acid is used to digest ilmenite (FeTiO 3) or ilmenite and titanium slag. After a ...

Titanium Dioxide Concrete Pigment

Titanium dioxide concrete and cement can eliminate smog in the air when exposed to ultraviolet light. In order to purify the smog in the air, nitrogen oxides must be converted into different, less harmful substances, such as nitrate ions. Nitrate ions formed during the reaction then can generate neutral salts, which can be washed away by precipitation. Although this reaction can happen ...

Titanium Dioxide vs. Zinc Oxide Sunscreens

Titanium dioxide is effective at blocking UVB and shortwave UVA rays, but it is less effective than zinc dioxide at blocking long UVA rays. Zinc oxide's ability to block various types of rays makes it one of the most effective sun protection products on the market at preventing sun damage. However, zinc oxide often is combined with additional UVB blockers to provide the most complete ...

Titanium Dioxide

Titanium dioxide power is very finegrained and it agglomerates, so glazes containing it need to be sieved to break down the small lumps (even a high speed propeller mixer often won't do it). Although titanium is the strongest white pigment known for many uses, in ceramics the whiteness (and opacity ) it imparts to glazes is due to its tendency to crystallize during cooling.
