Dark blue nano tungsten oxide is not only a new type of nano heat insulation material that can be used for heat insulating window glass, but also a raw material that can be applied in the reduction sintering process to prepare tungsten skeleton.
Some scholars have carried out related experiments on addition of blue tungsten oxide during the production of sintered tungsten skeleton. The experimental results show that:
1.0 The addition amount of blue tungsten oxide powder has a great influence on the density of the tungsten skeleton. As the amount of blue tungsten oxide powder added increases, the density of the tungsten skeleton decreases.
2.0 Reducing the particle size of the blue tungsten oxide powder enables better uniformity of the alloy structure after copper infiltration and lowers the sintering temperature of the tungsten skeleton at the same time.
3.0 The sintered tungsten skeleton added with blue tungsten oxide has low oxygen content. The tissue density after infiltration is more than 99%, and thermal conductivity can reach 231W/(m?K).
