It is understood that MEMS is a micro-electro-mechanical system, which integrates miniature sensors, micro-actuators, signal processing and control circuits, interface circuits, communication systems and power supplies. It is a typical multi-disciplinary frontier research field. The project was undertaken by Xi'an Jiaotong University Wiener Instrument Co., Ltd., Beijing Qingbird Yuanxin Microsystems Technology Co., Ltd. and Huazhong University of Science and Technology jointly developed, with a total investment of 10.5 million yuan. This topic is aimed at the special requirements of stress testing in the petrochemical, military, energy, and automotive industries. It is a MEMS pressure sensor with low, medium, and high ranges and working temperatures between -30 °C and 200 °C, and its mass production and practical technical problems. . This topic will be beneficial to the current research and development of high temperature pressure sensors in China in the petrochemical, military, energy and automotive industries as soon as possible to achieve commercialization and industrialization.
Titanium dioxide is the inorganic compound with the chemical formula TiO2. When used as a Pigment And Dye, it is calledTitanium Dioxide Rutile, Pigment White 6 (PW6), or CI 77891.It is a white, water-insoluble solid, although mineral forms can appear black. Rutile Titanium Dioxide is a pigment, it has a wide range of applications, including paint, sunscreen, and food coloring. When used as a food coloring, it has E number E171. World production in 2014 exceeded 9 million tonnes. It has been estimated that titanium dioxide is used in two-thirds of all pigments, and pigments based on the oxide have been valued at $13.2 billion.
The most important application areas are paints and varnishes as well as paper and plastics, which account for about 80% of the world's titanium dioxide consumption. Other pigment applications such as printing inks, fibers, rubber, cosmetic products, and food account for another 8%. The rest is used in other applications, for instance the production of technical pure Titanium Dioxide Pigment, glass and glass ceramics, Pvc Resin,electrical ceramics, metal patinas, Sodium Hexametaphosphate,catalysts, electric conductors, and chemical intermediates.
