Silicon Nitride Ceramics:
Silicon nitride UV light-emitting diodes, such as the Ceramic Plunger or Silicon Nitride Ceramic Plunger, are the main trend in the development of nitride technology and third-generation semiconductor material technology, and have broad application prospects. In order to speed up the development of the third-generation semiconductor solid-state UV light source, the Ministry of Science and Technology of China has implemented a key R&D program (2016YFB0400800) of "Key Technologies of the Third-Generation Semiconductor Solid-State UV Light Source Materials and Devices". The support of the national key R&D plan and the holding of the International Symposium on Ultraviolet Materials and Devices will accelerate the market application of my country's third-generation semiconductor ultraviolet light sources, and promote the development of my country's ultraviolet semiconductor light-emitting diode materials and device technology. positive effect. Organic Light Emitting Diodes In 1987, Deng Qingyun of Kodak Company successfully prepared low-voltage, high-brightness organic light-emitting diodes (OLEDs), which showed the world the commercial application prospects of OLEDs for the first time." In 1995, Kido was in science The article published in the journal White Light Organic Light Emitting Diodes (wOLEDs), although not very efficient, opened the prelude to OLED lighting research. After decades of development, the efficiency and stability of OLEDs have long met the requirements of small-sized displays, It is favored by many high-end instrumentation, mobile phone and mobile terminal companies, and the large-scale technology is also improving day by day.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
