Effects of Raw Materials on Morphology,Properties and Green Compact Strength of Tungsten Powder AITranslate
Abstract AITranslate
Tungsten powder was prepared from yellow tungsten oxide,blue tungsten oxide and purple tungsten oxide by fractional reduction.The effects of raw material types on the properties of tungsten powder and the green compact strength were systematically studied.The results show that under the same technological conditions,the tungsten powder prepared from purple tungsten oxide is the finest;the tungsten powder prepared from blue tungsten oxide is the coarsest;the tungsten powder prepared from yellow tungsten oxide is between the above two.Their particle sizes are 2.92μm,3.60μm and 3.06μm,respectively.The morphology of tungsten powder prepared from purple tungsten oxide is polyhedral and equiaxed while that of tungsten powder prepared from blue tungsten oxide is complex and diverse,and the particle size distribution of these two kinds of tungsten powder is wide(the diameter distance is 2.19).However,the tungsten powder prepared from yellow tungsten oxide has an irregular shape and a narrow particle size distribution(the diameter distance is 1.65).In addition,the green compact strength of tungsten powder prepared from blue tungsten oxide is the highest(5.4 MPa);that of tungsten powder prepared from purple tungsten oxide is the second(4.8 MPa);that of tungsten powder prepared from yellow tungsten oxide is the lowest(4.4 MPa).Therefore,the complex morphology of tungsten powder and wide particle size distribution are beneficial to the improvement of the green compact strength of tungsten powder.
