Abstract

PURPOSE:To obtain the titled composition giving a transparent glass film having fine appearance and causing little change in the resistance of an RuO2 resistor in a thick film circuit formed on a ceramic substrate by adding SiO2, B2O3, etc. to PbO as a base. CONSTITUTION:This glass composition for coating a thick film circuit consisting of RuO2, Ag-Pd, etc. on a ceramic substrate to protect the circuit contains, by weight, 3-7% SiO2, 15-25% B2O3, 65-75% PbO, 3-8% Al2O3 and <=5% Cr2O3. In case of conventional glass for coating, when RuO2 is printed and baked to form a resistor, the resistance value is considerably changed, and the formation of a circuit becomes impossible, so the glass can not be used to coat a thick film circuit contg. the RuO2 resistor. Said glass composition of this invention causes little change in the resistance value of such an RuO2 resistor, so a thick film circuit contg. the RuO2 resistor can be protected by coating the glass composition.

The organic solvent and the organic binder are used to make the glass composition into a paste state, and both of them scatter in the process when burned in the air, resulting in carbon. Therefore, the organic solvent is not particularly limited as long as it can scatter at temperatures below the baking temperature and does not react with the glass composition, and generally α
Terpineol, butyl carpitol, etc. are used. Conventionally, cellulose resin has been used as an organic binder, but if a large amount of cellulose resin is used in a glass paste, it will cause residual carbon and reduce transparency if the glass has a fusing temperature of 560°C or less. However, it has the disadvantage that it causes a change in color tone and impairs the aesthetic appearance. Also, if you reduce the use of cellulose resin binders,
It has the disadvantage that it significantly impairs the printability of glass paste and the strength after printing. Therefore, as a result of examining various binders, we found that by using an organic vehicle using an acrylic resin binder or a mixed binder of acrylic resin and cellulose resin, we could achieve a high transparency f1 (L).

When using a mixed binder of acrylic resin and cellulose resin, the weight of the 1]-s resin must be 1.2 times or less the weight of the acrylic resin, and the weight of the cellulose resin must be less than 1.2 times the weight of the acrylic resin. When the amount of resin is increased, baking may sometimes occur, requiring a holding time of 2 hours or more at 300 to 400° C. in order to scatter the cellulose resin. In this case, it was impossible to complete baking in a short time, and if the holding time for this scattering was not maintained, residual charcoal was formed, causing a change in color tone and a marked reduction in transparency. However, by setting the weight ratio of cellulose resin to acrylic resin to 1.2 times or less, it became possible to reduce the time required for temperature rise, baking, and cooling to one hour or less. Moreover, in the case of using only acrylic resin, this operation was completed in about 30 minutes.
