发明名称 PREPARATION METHOD OF DOPED COMPONENTS FOR MANUFACTURING OF TUNGSTEN WIRE
摘要 FIELD: metallurgy. ^ SUBSTANCE: invention relates to non-ferrous metallurgy and can be used at receiving of tungsten powder for preparation of tungsten wire. It is received alkaline silica- potassium basis by means of dissolution of silicic acid in potassium hydroxide at correlation "û:"=5.5-6.0 and boiling temperature. Received pulp is dissolved by water and neutralised by portions of hydrochloric acid up to pH=3-4 at intensive mixing up to coagulation of silicon compound. Into received basis there are introduced alloying elements. ^ EFFECT: it is provided simplification and acceleration of technology, reduction of material and labour expenditures. ^ 1 tbl, 1 dwg
