PROTECTIVE COATING FOR MUFFLE IN OPTICAL FIBER DRAW FURNACE
A muffle for an optical fiber draw furnace. The muffle including an inner surface and an outer surface, the inner surface forming an inner cavity. A protective coating is disposed on the inner surface, the protective coating having a melting point of about 1850° C. or greater. Furthermore, an absolute difference between a coefficient of thermal expansion of the protective coating and a coefficient of thermal expansion of a material of the muffle is 2.0 ppm/° C. or less over a temperature range from 25° C. to 1000° C.
