Additive for preparation of spherical titanium powder and using method thereof

The invention belongs to the surface and interface fields, and particularly relates to an additive for preparation of a spherical titanium powder and a using method thereof. The technical problem to be solved comprises that provided is the additive for preparation of the spherical titanium powder, and the additive is prepared by mixing evenly the following raw materials in parts by weight: 20-30 parts of sodium fluoride, 5-10 parts of potassium fluoride, 0.02-0.03 part of sodium cyanide, and 0.01-0.02 part of potassium cyanide. The additive can be added in a main salt to be used as an electrolyte during electrolysis, the spherical titanium powder can be prepared through electrolysis, the cost is low, and the operation is simple.
