Fired Silver Paint: Silver Oxide and Flux in Polyvinyl Alcohol and Water (Gray, Erie Resistor 1954, Ex. 2)

A paint for putting silver electrodes on ceramic, glass or mica. Silver oxide and a little ceramic flux are held in polyvinyl alcohol dissolved in water. The wet paint conducts electricity, so a capacitor can be measured while it is being painted. On firing, the silver oxide turns into a silver film held on by the flux. Gray found this paint so stable that it kept six months. Source: Robert B. Gray, US 2,695,275 (Erie Resistor, 1954), Example 2. Not given: which flux, and the firing heat. Bismuth subnitrate, one of the fluxes Gray names, is ours. Picture drawn by Youblob.

Dissolve 2 g polyvinyl alcohol in the water

For 100 g of paint: dissolve 2 g polyvinyl alcohol in the water, warming it to help it dissolve. The water is the balance, about 34 to 44 g. Warming is ours.

Grind in silver oxide and flux

Grind 50 g precipitated silver oxide and 2 to 10 g ceramic flux into the solution until smooth. Gray gives the flux only as a class; ours: bismuth subnitrate, one of the common fluxes he names. The right amount depends on the ceramic it will be fired onto.

Add 2 to 4 g alcohol against foam

Stir in 2 to 4 g ethyl alcohol. It stops the polyvinyl alcohol from foaming.

Store

Keep it in a closed jar. Gray found no reaction between the ingredients in six months, and the paint can stand for some hours in use without stirring.
