With a development history of nearly 50 year, the Research and Development Center of Shanghai Institute of Ceramics, Chinese Academy of Sciences, was a large-medium-scale national construction project during the seventh Five-Year Plan. The R&D Center of SIC was officially registered as an enterprise in 1993, and was acknowledged as a Shanghai Hi-tech Enterprise from 1994. The center was also awarded as Shanghai Garden Unit in 2002. Located in the Jiading District of Shanghai, the R&D Center covers an area of 42,000 square kilometers and has a building area of 39,000 square kilometers. At present, the R&D Center has 188 staff member on job, including 89 persons with junior college or higher diploma and 78 persons holding intermediate rank and advanced technical job title or more senior titles. The R&D Center is mainly engaged in the technical research and development of advanced inorganic materials, intermediate scaling-up experiments and pilot production, covering research, development and production of products and projects on advanced inorganic materials of artificial crystals, functional ceramics and structural materials.
Artificial crystal materials developed and produced by the R&D Center have won a high reputation at home and abroad. In the field of scintillation crystals, substantive research & development as well as pilot production have been conducted on BGO, BaF2, CeF3, PbWO4, PbF2, CsI, and other scintillation crystals, which could be widely used in high energy physics, nuclear physics, nuclear medication, security surveillance, suppress smuggling, geological prospect and other fields. The R&D Center holds the capacity of large-volume provision of crystals with quality of leading international standard.
The R&D Center has developed and realized volume production of some important piezoelectric crystals and laser crystals, including lithium tetraborate crystal (Li2B4O7) that could be utilized in high frequency devices such as SAW filter and resonators, tellurium dioxide crystal (TeO2) that could be utilized in acousto-optic devices such as acousto-optic deflector and modulator, barium titanate crystal (BaTiO3) that could be utilized in holographic storage, optical communication, image processing, and barium metaborate crystal (β-BaB2O4) that could be utilized in the frequency signaling, mixing and optical parameter oscillator for high-power pulse laser of ultraviolet.
With the rapid development of preparing technologies for artificial crystals, there are increasingly international demands on devices based on artificial crystals. As the core component of various detectors, artificial crystal materials play a significant role on these devices. In addition, higher and more updated requirements on artificial crystal materials have emerged under the expanding market and applications. Therefore, provision of integrated artificial crystal devices has become increasingly pressing. At present, there are following development trends for artificial crystal materials. Firstly, material quality and finished product rate shall be constantly improved so that cost could be substantially reduced to enter civil markets; secondly, crystal materials with innovative functions shall be further developed according to market demands; thirdly, processing technology for crystals shall be studied and advanced to strength the development of processing of crystal devices; fourthly, development level for devices shall be increased to persistently improve the device assembly quality. In the face of increasingly drastic international competitions, the problem regarding crystal material development, i.e. insufficient capacity of developing innovative materials with foresight and independent intellectual property rights, needs to be solved. Therefore, greater efforts shall be made to accelerate its development to realize the transition from simplex preparation of crystal materials to comprehensive fabrication of artificial crystal devices of various categories, so that more independent intellectual property rights and more efficient industrialization could be obtained.
In the field of functional ceramics, ceramic components and various devices based on PZT ceramics of various series have been developed and manufactured. Related products cover a broad scope of piezoelectric ceramics including lead zirconate titanate, barium titanate, lead metaniobate, and bismuth-containing layer piezoelectric ceramics, which have found wide applications in electro-acoustic devices, ultrasonic probe for medication, acoustic transducer, fish detector, ultrasonic washer, flowmeter, high temperature sensor etc.
In the field of structural ceramics, ceramic materials of Al2O3 and ZrO2 and related devices have been developed and manufactured. Possessing outstanding properties of high whiteness, good erosion resistance, high chemical stability, and excellent wearability, ceramic materials reinforced with zirconia have broad applications in mechanics, electronics, petroleum, chemical engineering, spaceflight, textile and other industries. Alumina ceramics have advanced performances including high density, good chemical stability, good wearability, high toughness, excellent impact resistance, and could be widely utilized in spaceflight, high pressure pump plunger, high accuracy sealing rings, wire drawing die, ore bucket teeth, valve core for petroleum bump and other hi-tech fields.
In order to ensure the constant improvement of product quality and to satisfy demands on product performance from various clients, the R&D center conducts its production processes under strict, standard and traceable conditions. The R&D center obtained ISO 9001 quality management system certification in 1999 and transferred to ISO9001:2000 certification in 2001, and have passed the supervision and examination in the next successive years.
