Ningbo rare flashes of low-cost high-performance materials ceramic industry key technology breakthrough

Flashing ceramics are a class of high-energy rays or particles to achieve UV - visible conversion of functional materials , medical imaging, security checks , oil and gas exploration, industrial inspection , and high-energy physics and other fields have a wide range of applications . CT is one of the largest application direction flashing ceramics , modern medical diagnosis as an important means of medical imaging plays an integral role in the diagnosis of cancer , cardiovascular , neurological , orthopedic and many other diseases on . The rare quality of CT imaging , detection efficiency and sensitivity of the detector performance by using direct flash ceramic decision.

Chinese Academy of Engineering, Ningbo Institute of Material Technology and optoelectronic materials and devices in the researcher江浩川team and the leadership of Jiang Jun , following the 2013 CT flashing around the ceramic nanopowders high sintering activity to optimize the design and preparation of the bulk of the breakthrough (J . Am. Ceram. Soc., 2013, 96 (10), 3038-3041), a low-cost high-performance rare earth flashes in recent industrialization of key technologies in the field of ceramic has achieved a major breakthrough , the successful implementation of large-size ceramic (60 mm × 140 mm) as well as the preparation of stable and controllable precision machining precision detection array. Meanwhile, verified by characterizing the United States, the Czech Republic and other countries and a number of authoritative research and testing organization , the key performance indicators of the team prepared ceramics such as light output , decay time , anti- radiation damage , such as with the international advanced level afterglow gem flashes body similar or better. These new breakthroughs in key technologies will further promote the CT technology provides a solid protection and technical support with the flashing ceramic industry.

Currently, around -related technology has been declared national invention patents 8 ; part of basic research results have been published (IEEE Transactions on Nuclear Science, 2014, 61, 301-305; IEEE Transactions on Nuclear Science, 2014, 61, 306-311).

The study was planned in Ningbo materials personnel , Ningbo City, 3315 and other funds to support the innovation flagship team .
