ABSTRACT:
This invention relates to aluminum phosphate refractory cement compositions which comprise a mixture of aluminum phosphate containing excess phosphoric acid, relatively small particle size alumina and a mixture of relatively medium and coarse particle size inert filler materials. This cement is useful for cementing tungsten-halogen lamps into glass reflectors. The aluminum phosphate is formed with an excess of phosphoric acid which reacts with the alumina when the cement is baked at elevated temperatures.
