Abstract:
1. A method of making a fused silica glass article having a near-net shape, the method comprising the steps of: a. providing a mandrel, the mandrel having a shape that is complementary to the near-net shape, wherein the mandrel acts as a susceptor for radio-frequency radiation; b. providing silica soot particles; c. depositing the silica soot particles in situ on the mandrel to form a silica soot body, the silica soot body comprising the silica soot particles; d. inductively heating the mandrel with radio frequency radiation to a temperature in a range from about 1200° C. up to about 1900° C.; and e. sintering the silica soot body in situ on the mandrel to form the fused silica glass article.
