Mechanism and functional efficacy of TiO2 nanopowder

As a sensor material: TiO2 nanopowder can be used not only for moisture sensitive and pressure sensitive components, but also as a sensor material for detecting multiple gases.
TiO2 nanoparticle as a catalyst carrier: Since researchers discovered strong interactions between certain metals and TiO2 carriers in 1978, most of the scientists in the field of catalysts in various countries have used TiO2 as a catalyst carrier.
As a photocatalyst: TiO2 is strongly redoxed due to its stable chemical properties.
It is widely used as a catalyst for photocatalytic oxidation reaction because it is resistant to photocatalytic corrosion, insoluble, non-toxic, and low in cost. Experiments show that nano-TiO2 can be used for at least 12 times of repeated use to keep the photodegradation efficiency basically unchanged, and maintain its photoactivity under continuous light for 580 minutes. Therefore, it has broad development prospects for its practical application.
Sterilization: Nano TiO2 powder is an inorganic antibacterial agent, non-toxic, odorless, non-irritating, good in thermal stability and heat resistance, non-combustible, and effective.
Used as a raw material for solar cells: TiO2 nanoparticle is an important semiconductor material that is inexpensive, completely pollution-free and stable. It has a band gap of 3.2eV and absorbs ultraviolet light. Swiss scientists have used the organic compound of excessive metal Ru as a dye and a suitable oxidation-reduction electrolyte to produce a TiO2 battery with a photoelectric conversion efficiency of 7.1% under sunlight, and its low cost has caused many The interest of research workers.
Nano TiO2 particle can be used as an anti-UV additive: In the past, sunscreens were mostly organic compounds. This year, a group of inorganic powders such as nano-ZNO, TiO2 and iron oxide red have been favored. Because they are non-toxic, tasteless, non-irritating to the skin, do not decompose, do not degrade, have good thermal stability, and nano ZNO, TiO2 itself is white, can be easily colored, and has strong UV absorption ability, so it is widely used in various types. In the daily chemical products.

What is silicon carbide whiskers and its application

Silicon carbide whiskers are a kind of single-crystal fiber with a certain length-to-diameter ratio, which has very good high temperature resistance and high strength. It is mainly used in toughening applications where high temperature and high strength applications are required. Such as: aerospace materials, high-speed cutting tools. At present, it has a very high performance-price ratio. Silicon carbide whiskers are cubic whiskers, and diamonds belong to a crystal form. They are the whiskers with the highest hardness, the largest modulus, the highest tensile strength and the highest heat resistance temperature. It is both α-type and β-type, in which β-type performance is better than α-type and has higher hardness (Mohs hardness of 9.5 or more), better toughness and electrical conductivity, anti-wear, high temperature resistance, especially earthquake resistance Corrosion-resistant, radiation-resistant, has been applied to aircraft, missile casings and engines, high-temperature turbi...

What is boron nitride coating and how to use it?

Product Characteristics Environment Friendly: Boron nitride is environmentally friendly, non-toxic, non-polluting Chemical Properties:  Strong non-stick properties in high temperature environment, stability in high temperature Physical Properties: Electrical insulator, low dielectric constant, good thermal conductivity and high lubricity Product Features: Special formula, water-based, easy to use, long-acting formula This type of coating is suitable for all kinds of release agents which need to be operated at high temperature (the product can withstand high temperature of 2800 C). For example, glass industry, metal welding industry, etc., can effectively lubricate and isolate the interface, which can make the processing more smoothly. Sintering of metal and ceramic powders is usually carried out on graphite plate. After coated with boron nitride coating on graphite, the pollution, reaction and bonding phenomena of carbon on sintered parts which may ...

We have already used titanium dioxide powder in our lives.

Titanium is a chemical element, chemical symbol Ti, atomic number 22, located in the fourth cycle of the chemical periodic table, group IVB. It is a silver-white transition metal characterized by light weight, high strength, metallic luster and resistance to wet chlorine gas. The most common compound of titanium is titanium dioxide, which can be used to make white pigments. In the past, people used to mine titanium ore, the main purpose is to obtain titanium dioxide. 1.The nature of titanium dioxide Titanium dioxide (chemical formula: TiO2) is a white or bulk amphoteric oxide with a molecular weight of 79.83. Titanium dioxide is a compound of titanium, a pure substance composed of two or more elements (different from elemental matter). A compound has certain properties, different from the elements or ions it contains, and other compounds. Properties of crystal form: TiO2 has three main crystal forms such as rutile type, anatase type and plate titanium type. Optical properties: Since T...
