查询词典 powder

The invention relates to an electrochemical method for preparing ultra-fine tantalum powder, wherein it uses the mixture slat flux with CaCl2 or CaCl2 as electrolyte; composites Ta2O5 powder/block with metal collector as solid cathode; uses graphite or inertia anode as anode; uses reference polar to control the electrolysis level, under inertia gas to electrolyze at 500-1000Deg. C; and the electrolysis time should make electrolysis electricity reach needed amount; reduces Ta2O5 into ultra-fine metal tantalum powder.

The results showed that the irradiation treatment in the dose of 2.0-8.0kGy is not significantly effective to the contents of total sugar, crude protein and crude fat in walnut powder. The content of crude fiber in irradiated walnut powder increased, but not significantly. The irradiation had barely change on the contents of the lauric acid and myristic acid, and non-significant effects on the contents of palmitic acid, palmitoleic acid, stearic acid, leinoleic acid, arachidic acid and linolenic Acid. However, the irradiation contributed to significant increase in the content of oleic acid with the irradiation dose. When irradiation dose reached 8.0kGy, the content of oleic acid had an increase of 4.3%. Irradiation will not change the sensory index of walnut powder much when irradiation dose is lower than 8.0kGy.
