Less than 10,000 tons a year worldwide,High performance aluminum nitride powder is difficult to produce,why?

Aluminum nitride (AlN) ceramics have good thermal, electrical, mechanical and chemical stability, and are now more ideal substrate materials and electronic packaging materials. The excellent performance of AlN ceramics is directly related to the performance of raw material powder, and the high performance AlN powder is the key to prepare high thermal conductivity AlN ceramics. In foreign countries, the manufacturing process of AlN powder has been quite mature and the commercialization degree is also very high. Previously, according to the [...]

Sodium titanate holds graphene together to create a high energy, high power micro capacitor

With sea urchin sodium titanate as the negative pole and porous activated graphene as the positive pole, what kind of “spark” will be generated when they combine? According to the dalian Institute of Chemical Physics, Chinese Academy of Sciences, wu Zhongshuai’s team and Bao Xinhe’s team worked together to combine “sea urchins” with graphene to develop flexible sodium ion micro-supercapacitors with high energy density and high heat resistance. Micro miniature sensors, micro robot, the power supply system is inseparable from [...]

The high precision isotope ratio analysis of ultramicro strontium samples can be realized by using silicotungstic acid as the emitter

Strontium isotope ratio (87Sr/86Sr) has been widely used in earth science, astrochemistry, environmental chemistry, food origin tracing, archaeology and other fields. Since the 1960s, the Thermoelectric ionization mass spectrometer (TIMS) has been regarded as the benchmark technique for ratio analysis of 87Sr/86Sr with excellent accuracy and high sensitivity. Excellent sensitivity is the prerequisite for the analysis of high precision 87Sr/86Sr ratio in ultramicro samples. The key to improve the sensitivity lies in the selection of suitable emitters to improve [...]

Vanadium dioxide — a revolutionary material for the future electronics industry

Because of its unique properties, vanadium dioxide has become an ideal choice to replace silicon for a new generation of low-power electronic devices. Swiss researchers recently demonstrated the application of vanadium dioxide to aerospace communications (600677) systems to achieve programmable rf electronics, highlighting the oxide’s potential. Vanadium dioxide has phase transition characteristics and forms that can be converted between an insulator and a metal, acting as an insulator at room temperature and as a metal conductor above 68 degrees Celsius. [...]

The technology of industrialized production of nanometer copper powder has developed by Chinese manufacturer

The bulk application of nanometer copper powder in the market is based on the cost. At present, the high cost cannot realize the mass application, and the reason for the high cost is that the industrial production of ordinary equipment cannot be realized. Therefore, the first problem we solved is to use ordinary conventional equipment to realize the industrial production of nanometer copper powder. If the cost problem is not solved, even the preparation of high purity, ultra-fineness, narrow [...]
