titaniumdioxide.eu Titanium dioxide occurrences in nature are never pure; it is found with contaminant metals such as iron. Titanium dioxide is thus added to paints, cements, windows, tiles, or other products for sterilizing, deodorizing and anti-fouling properties and is also used as a hydrolysis catalyst. Titanium dioxide white paint was used to paint the Saturn V rocket, which was the first rocket to send astronauts to the moon. www.titaniumdioxide.eu   (816 words)

Titanium dioxide - Wikipedia, the free encyclopedia Titanium dioxide occurrences in nature are never pure; it is found with contaminant metals such as iron. Titanium dioxide is the most widely used white pigment because of its brightness and very high refractive index (n=2.4), in which it is surpassed only by a few other materials. Titanium dioxide, particularly in the anatase form, is a photocatalyst under ultraviolet light. en.wikipedia.org /wiki/Titanium_dioxide   (583 words)

natural organic make-up - Titanium Dioxide: Toxic or Safe?   (Site not responding. Last check: 2007-11-03) Titanium dioxide is the subject of new controversy, yet it is a substance as old as the earth itself. Titanium dioxide is regarded as an inert, non-toxic substance by many regulatory bodies such as the MSDS (Material Safety Data Sheets) and others charged with the responsibility of safeguarding the health of occupational workers and public health. Titanium dioxide particulates were not detected in the blood, liver, kidney or urine and no adverse effects were noted from its ingestion. www.organicmakeup.ca /CA/titaniumdioxide.asp   (1399 words)

EPA: Federal Register: Titanium Dioxide; Exemption from the Requirement of a Tolerance Titanium dioxide is an opaque powder that is approved for use as a colorant in food (21 CFR 73.575), in drugs (21 CFR 73.1575), and in cosmetics (21 CFR 73.2575; 21 CFR 73.3126). Indeed, titanium dioxide is frequently used as a negative control material in in vivo chronic dust exposure studies and in in vivo assessments of fibrogenic potential of dusts. Titanium dioxide is exempted from the requirement of a tolerance for residues in or on growing crops, when used as an inert ingredient (UV protectant) in microencapsulated formulations of the insecticide lambda-cyhalothrin at no more than 3.0% by weight of the formulation. www.epa.gov /fedrgstr/EPA-PEST/1998/March/Day-25/p7492.htm   (2471 words)

Titanium (EHC 24, 1982) Titanium dioxide is extensively used as a white pigment in paints, enamels, plastics, and cosmetics as well as a colouring agent in food. Titanium dioxide is a frequently used compound in lung clearance studies, where a biologically inert substance is required. Since titanium coheres with iron in most samples, and the ratios found were constant and close to the geochemical average of the ratios of these elements in soils, it was suggested that titanium had originated mainly from a soil source (yielding particles of 1 µm). www.inchem.org /documents/ehc/ehc/ehc24.htm   (16046 words)

The Hindu : Tisco-TN MoU for titanium dioxide project Subject to technical and commercial viability, the Tisco is expected to put up a 60,000-tonne per annum integrated titanium dioxide facility in two phases on a total outlay of Rs.1,600 - 1,800 crores. Production of titanium proved costly and, hence, "not useful to mankind.'' As and when a cost-effective process emerged, titanium could be produced at the cost of steel and could become useful. The Tisco foray into titanium dioxide was seen in the context of the titanium potential to emerge as a major future metal and the company preparing itself eventually to make titanium. www.hindu.com /2002/06/28/stories/2002062801340500.htm   (644 words)

Titanium Dioxide Pigmentary titanium dioxide, as used by the paper industry, usually consists of semi-spherical particles having diameters all very close to the range 0.25 to 0.4 micrometers. Premature mixing of titanium dioxide slurry with alum or other cationic materials should be avoided in order to minimize self-agglomeration of the pigment. Some of the negative features of titanium dioxide are (a) relatively high abrasiveness, and (b) absorption of ultraviolet light, reducing the effectiveness of fluorescent whitening agents. www4.ncsu.edu /~hubbe/TIO2.htm   (479 words)
