Abstract

PURPOSE:To obtain high purity phosphate glass with superior optical properties and high water resistance for a light transmission line by vapor-phase-reacting a III group element cpd. such as a Ga, B or Al cpd. with a P cpd. and melting the reaction product together with a Ge or Si cpd. CONSTITUTION:Liquid POCl3 in container 1 and liquid GaCl3 in container 2 are taken out of pipes 5, 6 with bubbling gases 3, 4 such as Ar and mixed. O2 gas 7 is added to the mixed gas and introduced into torch 9. By a high temp. of oxyhydrogen flame 12 formed by igniting O2 gas 10 and H2 gas 11 introduced into torch 9, the POCl3 and GaCl3 are vapor-phase-reacted to deposite GaPO4 soot 13 on the inside of crucible 14. This GaPO4 is then melted together with a Ge or Si cpd. and vitrified.
