rutile titanium dioxide r996 white pigment

Inductively coupled plasma-optical emission spectrometry (ICP-OES) is another popular method for determining barium in TiO2. This technique uses an inductively coupled plasma to ionize the sample and then measures the intensity of light emitted by the resulting ions. ICP-OES offers high sensitivity and wide dynamic range, allowing for the detection of trace amounts of barium. It also requires specialized equipment, but its automation capabilities can reduce costs and improve efficiency.

In conclusion, the rutile type TiO2 stands out for its robust physical and chemical properties, which translate into a myriad of practical applications. From enhancing the performance of industrial coatings to aiding environmental clean-up efforts, rutile continues to be a cornerstone material in modern industry and science. As research progresses, it is likely that new uses for this remarkable substance will be discovered, further cementing its status as a versatile and indispensable material.

TiO2 has been well accepted in the food industry and can be found as the E171 additive in various food products, mainly for whitening and texture. It is present in some cottage and Mozzarella cheeses, horseradish cream and sauces, lemon curd, and in low-fat products such as skimmed milk and ice-cream. Even if the product is labelled as containing E171, no information is usually given about the quantity, particle size and particle structure. FDA claims that TiO2 may be safely used as a colour additive for colouring foods in quantities up to 1 % by weight of the food. Interestingly, TiO2 is frequently declared as a “natural colouring agent” and is therefore well accepted by consumers.

In a 2016 study published in Scientifica (Cairo), Egyptian researchers examined the effects of titanium dioxide nanoparticles on the organs of mice by orally administering the food additive daily, for five days. The results showed that the exposure produced “mild to moderate changes in the cytoarchitecture of brain tissue in a time dependent manner.” Furthermore, “Comet assay revealed the apoptotic DNA fragmentation, while PCR-SSCP pattern and direct sequencing showed point mutation of Presenilin 1 gene at exon 5, gene linked to inherited forms of Alzheimer’s disease.” The researchers wrote: “From these findings, “the present study concluded that TiO2NPs is genotoxic and mutagenic to brain tissue which in turn might lead to Alzheimer’s disease incidence.”

In the realm of pigments, titanium dioxide's ability to reflect light across the visible spectrum makes it an ideal candidate for brightening products. It is widely used in paints, plastics, paper, inks, food coloring, and cosmetics. The addition of TiO2 not only enhances the whiteness but also improves the durability and opacity of these materials. Moreover, its non-toxic nature ensures that it can be safely used in products that come into direct contact with humans, such as food colorants and cosmetics.
