Research on nano aluminum nitride in thermal conductive plastics

1. Heat-conducting silica gel and epoxy resin: Ultra-high thermal conductivity nano-aln composite silica gel has good thermal conductivity, good electrical insulation, wide electrical insulation service temperature (working temperature -60℃- 200℃), lower consistency and good construction performance. Products have reached or exceeded imported products, because can replace similar imported products and widely used in electronic devices heat transfer medium, improve work efficiency. Such as CPU and radiator gap, high-power audion, thyristor element, diode, and the substrate contact with the thin seam [...]

Thermal and optical properties of nanometer tin oxide

In terms of thermal properties, nano SnO2 can be attributed to an ATO raw material, and its heat insulation mechanism: The SnO2 crystal has a regular tetrahedral rutile structure, and the anion coordination number is 6∶3. Each tin ion is adjacent to 6 oxygen ions, and each oxygen ion is adjacent to 3 tin ions. After antimony doped ions in SnO2, occupy the position of the lattice Sn4 +, forming a positive charge one price center SbSn and an extra [...]
