Nanometer blue tungsten oxide for ceramic microsphere may be produced stably by adjusting other process parameters without inletting H2 or NH3. Then, observe the effect of reduction time on blue tungsten oxide. And it is found that: The effect of reduction time on blue tungsten oxide is as follows: With the extension of reduction time, the oxygen index (O/W) shows a downward trend, and residual ammonia also shows a downward trend. But the effect of test temperature is much greater…
