Abstract

A method is described for self-spacing between two plate glasses by applying sealing materials during the gas panel sealing procedure. The method is more conveniently used in a smaller size panel, such as a 240-character panel, in which the spacers are currently used only near the edge of the panel. The method includes the following:

Self Spacing by Sealing Glass Composite

A method is described for self-spacing between two plate glasses by applying sealing materials during the gas panel sealing procedure. The method is more conveniently used in a smaller size panel, such as a 240-character panel, in which the spacers are currently used only near the edge of the panel. The method includes the following:

1. Refractory filler particles, preferably spherical, are sieved to limit the maximum particle size to the size of the space required in the gas panel sealing. To apply the method most effectively, the particle size distribution of the refractory filler should be maximum at the required panel spacing.

2. Sieved refractory particles are added to solder glass powder, either vitreous or devitrifying, and the mixture is blended well. Then, the admixed powder is applied on the seal area of the plate glass by one of the known methods, such as pasting, printing or transfer-tape technique.

3. No spacers are needed at least in the area near the seal. An appropriate loading weight is placed on a top plate, and the entire assembly is heated to complete the sealing. The solder glass will flow until the two glass plates pinch the refractory particles having maximum diameter, which corresponds to the space size required.

The refractory filler could be various kinds of simple or compound oxides and glasses. If the sealing glass is a devitrifying one, the particles of the devitrified sealing glass itself can b...
