Dark blue nano tungsten oxide for thermal insulating glass material can be added to the sintered tungsten skeleton for improving the thermal conductivity of the obtained alloy material. This is because when the sintered skeleton is added with blue tungsten oxide powder, the reduction of the interface energy and the water vapor generated during the process can ensure the smooth formation of the bore diameter, and thus build a complete continuous copper network, which can improve the thermal conductivity. However,…

Blue tungsten oxide nano powder may be used for preparing infrared absorption material, which is widely used in heat insulating window glass, including building, automotive, and so on. Blue tungsten oxide is also a kind of material that can be added to sintered tungsten skeleton. Through comparison experiments, the researchers found that thermal conductivity of the composite obtained by sintered tungsten skeleton of blue tungsten oxide after copper infiltration is higher, while addition of fine tungsten powder in sintered tungsten…

Blue tungsten oxide nanopowder may not only be applied for producing infrared absorption material, but be added to the sintered tungsten skeleton, so that the density of the subsequent alloy is increased. The researchers found that the structure did not have significant pore residue after addition of blue tungsten oxide on tungsten skeleton and copper infiltration. They analyzed the relevant reasons and found that there are three main points: 1.0 Tungsten powder in the skeleton cannot form a necking very…

Nano blue tungsten oxide may not only be applied for producing infrared absorption material, but also be added to the sintered tungsten skeleton for increasing the density of the tungsten skeleton after copper infiltration. When the skeleton added blue tungsten oxide powder is reduced and sintered under the H2 atmosphere, the blue tungsten oxide is reduced to fine grain size tungsten powder. While if fine particle size tungsten powder is directly added to the sintered tungsten skeleton, the density of…

Blue tungsten oxide powder, also known as WO2.92, is a new type of infrared absorption material. Certainly, blue tungsten oxide may also be added to the sintered tungsten skeleton to increase the density of the skeleton. When the skeleton of blue tungsten oxide is reduced and sintered under a hydrogen atmosphere, the blue tungsten oxide is reduced to fine grain size tungsten powder. In order to study the effect of adding blue tungsten oxide into sintered tungsten skeleton on copper…

Blue tungsten oxide powder for infrared absorption material may be added to the tungsten powder, and then be sintered to obtain a tungsten skeleton. Some researchers have mixed blue tungsten oxide powder (the particle size of the three BTO samples is more and more smaller) of different particle sizes with a mass fraction of 10% and 2μm tungsten powder, and then sintered at 1400°C. The density of the skeleton after sintering was 50.54%, 58.26%, and 59.11%, respectively. As can be…

Blue tungsten oxide for infrared absorption material may be added to tungsten powder, and therefore be applied for sintering tungsten skeleton. 11.22μm of blue tungsten oxide powder with a mass fraction of 5%, 10%, and 15% was added to 2μm of tungsten powder, respectively. And the mixing powder was performed reduction sintering at 1300~1500°C. How does the density of the obtained tungsten skeleton change? Under the same molding pressure, the density of the skeleton compacts with different blue tungsten oxide…

Blue nano tungsten oxide for infrared absorption material can be added to the process of preparing tungsten skeleton by the reduction sintering process. What is the effect of addition of blue tungsten oxide powder on sintering and infiltration of the tungsten skeleton? Some researchers have done the following related experiments to study the influences: 1.0 Prepare the raw materials – Tungsten powder (particle size of 0.4μm, 1μm and 2μm, respectively) and blue tungsten oxide (particle size of 11.22μm). The powders…

Dark blue nano tungsten oxide not only may be applied for producing infrared absorption material, but can be used to treat the problem of tungsten skeleton with high pre-sintering temperature and the existence of closed cells. Some researchers have added a certain amount of blue tungsten oxide powder to tungsten powder. According to the reduction characteristics of blue tungsten oxide powder, tungsten powder of different particle diameters is formed during the reduction process, and the reduction of the interface energy…

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…
