| 摘要 | PURPOSE: To obtain heat resistant aluminum phosphate cement useful for joining a tungsten halogen lamp to a glass reflector by compounding aluminum phosphate, alumina and heat resistant filler which are respectively specific. CONSTITUTION: This compsn. contains a mixture composed of (a) the aluminum phosphate contg. excessive phosphoric acid, (b) the alumina of a fine grain size and (c) the inert heat resistant filler of an intermediate grain size and coarse grain size. The compounding range of (a) 4 to 15 pts. vol. alumina, (b) 5 to 30 pts. vol. intermediate grain size filler, (c) 40 to 75 pts. vol. coarse particle filler and (d) 10 to 25 pts. vol. aluminum phosphate expressed as the total reaction product obtd. by bringing the aluminum hydroxide into reaction with 85% phosphoric acid, by defining the total volume of the slurry or paste as 100 pts. vol. is generally adopted for the amts. of the respective components to be used for forming the compsn. described above.
