The antimon-doped SnO2, SnO2 insulating material, system on aluminum metal base

Abstract

SnO₂ materials are attracting the attention of many scientists, because nano-sized SnO₂ materials are applied to sensor, new energy, semiconductors field, etc. A typical application when coating SnO₂/Sb₂O₃on aluminum substrates is as a thermally conductive insulating material for electronic components such as IC cooling, microprocessors, leds, .... When changing factors such as pH solution, dipping time, calcination and calcination temperature, the structure and morphology also change, leading to changes in physico-chemical properties. The research on synthesizing nano SnO₂/Sb₂O₃ (0.6%) by hydrothermal method brings very good results because this material has both insulating ability and high chemical and electrochemical strength, low toxicity to environment.

Aluminum base is a material with mechanical strength (plasticity, malleability), high chemical resistance, good heat dissipation. When coated with SnO₂/Sb₂O₃on an aluminum base, this material can become a heatsink integrated board for accessories and electronic equipment (resistance value from 5÷ 15MW, thermal conductivity reaching 93.4% efficiency).
