Abstract: A process for manufacturing a sealing glass composition consisting essentially of the following ingredients in the following proportions:

The process comprises the steps of providing the batch of ingredients to the above proportions and insuring a full mixture or mixing of the same. Thereafter, in one embodiment of the process, the batch may be heated to between 750 and 850*C to form a liquid melt and then the liquid melt is further heated until the temperature is 1,100 + OR - 20*C. The temperature of the melt is held between the aforementioned limits for a period of at least 3 hours and no longer than 3 1/2 hours, and thereafter the temperature of the melt is lowered to effectively inhibit bubbling of the liquid melt, and then the melt is removed for further processing.

Abstract: A copper oxide containing seal glass is formed by a controlled low temperature process which reduces the formation of seeds in the glass. In one embodiment the glass is prepared in two portions with the first portion containing the high melting oxides and the second portion containing the low melting oxides. The copper oxide is added to the second portion and the two portions are combined to form the seal glass at temperatures below about 800 DEG C which reduces the formation of Cu2O crystals in the glass.

Abstract: A method for forming an oxidized chromium film on the surface of chromium metal in a controlled manner which involves the use of a permanganate solution. The chromium metal film is first subjected to a basic hydrogen peroxide solution. The chromium surface is then removed from the hydrogen peroxide solution and immersed in an aqueous permanganate solution maintained at a temperature less than about 100 DEG C. for a time preferably within 1 to 5 minutes. At this time the chromium film has been oxidized to the desired thickness depending upon the time and temperature at which the surface has been subjected to the solutions. The surface is removed from the permanganate solution and dried. Should additional thickness of chromium oxide films be desired, the surface is intermittently subjected to the permanganate solution and dried to build up the desired thickness of chromium oxide.
