Titanium Carbide Ring
Chemical element, Ti, atomic number 22 and atomic weight 47. 90. While chemical behavior shows many similarities with that of silicon and zirconium, as an element of the first transition group, the chemistry of the aqueous solution, especially the lower oxidation states, has some similarities with that of chromium and vanadium. The main valence state 4 +, but also know the states 3 + and 2 +, which are less stable. The element burns in air when heated to obtain the dioxide, TiO 2, and when combined with halogens. Reduce water vapor to form carbon dioxide and hydrogen, and reacts with hot concentrated acids like, although it forms hydrochloric acid trichloride. The metal absorbs hydrogen to give approximate composition of TiH 2, and forms the nitride, TiN, and carbide, TiC. TiS2 are known sulfur and oxides lower Ti2O3 and TiO, and sulfides Ti2S3 and TiS. Salts are known of the three valence states. Titanium dioxide, TiO 2, is commonly found in a black or brown known as rutile. The natural forms found in nature are less than the anatasita and brooquita. Both the anatasita pure rutile are white. The black basic oxide, FeTiO3 is found naturally as the mineral ilmenite, this is the main commercial source of titanium. Titanium dioxide is widely used as white pigment in paints outdoors by being chemically inert, for its great covering power, opacity to UV light damage and self-cleaning ability. Dioxide has also been used as a bleaching agent and opaque porcelain glazes, giving a high gloss finish, hardness and acid resistance. Alkaline earth titanates have some remarkable properties. Dielectric constant level ranges from 13 for the MgTiO3, and several thousand for solid solutions of SrTiO3 in BaTiO3. The barium titanate also has a dielectric constant of 10,000 about 120 ° C (250 º F), which is its Curie point, has low dielectric hysteresis. The transducers ceramics containing barium titanate compare favorably with Rochelle salt and quartz, with respect to thermal stability in the former case, and the strength of the effect and the ability to form the ceramic in various forms in the second case. The compound has been used as a generator of ultrasonic vibrations and a sound detector. Elemental titanium carbide ring and titanium carbide ring dioxide have a low level of toxicity. Laboratory animals (rats) exposed to titanium carbide ring dioxide by inhalation have developed small localized areas of dark dust deposited in the lungs. Excessive exposure in humans may result in slight changes in the lungs. Effects of overexposure to titanium carbide ring dust: Inhalation of dust may cause tightness and pain in the chest, coughing and difficulty breathing. Contact with skin and eyes may cause irrritación. Route of Entry: Inhalation, skin contact, eye contact. Carcinogenicity: The International Agency for Research on Cancer (IARC) has included titanium carbide ring dioxide group 3 (the agent is not classifiable as to carcinogenicity in humans). . . .
