CONDUCTING SILVER POWDER-BASED PASTE, METHOD OF PREPARING SILVER POWDER, AND ORGANIC BINDER FOR THE PASTE Russian patent published in 2001 - IPC

FIELD: electronic engineering. SUBSTANCE: group of inventions relates to production of gas panel displays. High resolving ability thereof is provided by (i) using, in conducting paste, silver powder with particle size 0.1 1 mcm prepared by reduction for 10-25 min of 0.1-1.18 M silver nitrate aqueous solution with reducing agent including hydroquinone, trisodium citrate, sodium hydroxide, and ethanol taken in weight ratio 1:(0.5- 0.4):(0.1-0.3): (1-3) and (ii) using organic binding agent containing, wt parts: ethylcellulose 5-7, butyl carbitolacetate 83-91, Stearox 6 - 1-4, and oleic acid 3-6. EFFECT: enabled formation of high-quality double-layered conductors with high resolving ability and thickness less than 10 mcm due to use in the paste of fine functional material and introduction of plasticizing additives reducing structurization of paste. 3 cl, 1 tbl, 6 ex
