Rutile Titanium Dioxide Nanoparticles: Description, Usage, and Applications

Titanium dioxide is also called titania which occurs oxide of titanium in nature, and its resources are ilmenite, rutile, and anatase. It is a large-band gap semi-conductor. In 2014, world production exceeded nine million metric tons, and it has been valued at $13.2 billion. Since it has unique optical and chemical properties, titanium dioxide nanoparticles have been studied and numerous applications are found. They are also called ultrafine titanium dioxide. Small size add a significant property to nanoparticles of titanium oxide which makes it photocatalytic material. High chemical stability, and strong oxidizing power are also properties of titanium dioxide nanoparticles among others.

In consideration of being a rutile titanium dioxide nanoparticles as you can see the structure in the figure above, the nanoparticle one is more absorbent than larger size, and it has many synthesizing methods like Laser Ablation method. Since the band gap of rutile titanium dioxide nanoparticles is 3 eV which is lower than band gap of zinc oxide, and it has already applications in semiconductor technology as sensors. Therefore, rutile titanium dioxide nanoparticles are commonly studied in photonics, and semiconductor technology. It can be functionalized to absorb UV radiation in commercial applications. It can be additive or component of composites to insert photocatalytic activity to composites. One can also mix rutile and anatese to make band gap alignment.
A research group at Changwon National University conducted a study that they synthesized rutile titanium dioxide nanoparticles using sol-gel method followed by hydrolysis of TiCl4 at low temperature. They also found that the size is 26.4 nm at 300 C°, and the size increase with temperature. Another research group studied photocatalytic applications of room temperature rutile titanium dioxide nanoparticles, and they concluded that it shows a remarkable photocatalytic efficiency on degradation of MB Dye, RB Dye, and PNP. They examined the degradation of materials via UV-Vis spectrophotometry. As a result, degradations of MB Dye, RB Dye, and PNP are 97%, 98%, and 80% respectively.
Rutile titanium dioxide nanoparticles offer tremendous applications in many fields. There are researchers conducting experiments to develop new and cost effective synthesis methods, and many more applications will be found.

Usage of Silver Conductive Adhesive Paste in Corrosion Protection

In electronics, solders are main material to connect electrical components to substrates which are generally printed circuit boards. Although they are cheap, they are not effective if long term performance is considered since solders have low resistivity to corrosion relatively. Since corrosion reduce reliability, the cost of advanced technological systems such as RADAR, SONAR, LIDAR and more increase. In addition, small signals can be lost, and in huge data transfer, some of the data can be lost also especially which may lead catastrophic failures in critical systems. For instance, surface to air missiles can be launched to target which is not exist if the data coming from detection systems is noisy. Therefore, corrosion protection is necessary, and  silver conductive adhesive paste  is an essential candidate to replace PbSn solders due to its resistivity to corrosion. Silver conductive adhesive paste provide not only noisy reduction but also electromagnetic interference whi...

Titanium Carbide Powders and Applications

Titanium carbide which has the chemical formula of TiC attracted great interest for many structural applications due to its extremely high melting temperature, high hardness, high chemical resistance and good electrical conductivity. Therefore titanium carbide can be used in cutting tools, grinding wheels, wear-resistant coatings, high temperature heat exchangers, magnetic recording heads, turbine engine seals, and bullet-proof vests, etc. In addition, a promising field of application comprises plasma and flame spraying processes in air, where titanium carbide-based powders show high-phase stability. TiC(Titanium Carbide Powder) (325 mesh, 99,9+%)  can also be used in biomedical implant devices. Materials used for biomedical implant devices must satisfy a variety of property demands, which are often mutually exclusive. Further, different parts of a device demand different material properties. These factors often make it difficult to manufacture a medical device using a...

Difference between Anatase and Rutile Titanium Dioxide (TiO2) Nanoparticles

Titanium oxide  is the one of the top 50 chemicals which are produced in worldwide. It occurs in nature in three forms anatase, rutile and brookite. However, commonly, anatase and rutile forms have been used and studied. Naturally, it has whitish and opaque appearance, and through purification, it becomes whiter. Difference in crystal structure of these two forms as you can see in Figure 1 aroused interest in discrepancies between these forms, and many studies have been conducted. Figure 1: Crystalline structure of titanium dioxide anatase (a) and rutile (b) Ti and O atoms are represented in white and red respectively.                                                                                                P.
