Abstract
A device for manufacturing SiO2—TiO2 based glass by growing a glass ingot upon a target by a direct method. The device includes the target, comprising a thermal storage portion that accumulates heat by being preheated, and a heat insulating portion that suppresses conduction of heat from the thermal storage portion in a direction opposite to the glass ingot.
Claims2
A device for manufacturing SiO2—TiO2 based glass by growing a glass ingot upon a target by a direct method, comprising:
- the target, comprising
- a thermal storage portion that accumulates heat by being preheated, and
- a heat insulating portion that suppresses conduction of heat from the thermal storage portion in the direction opposite to the glass ingot,
- wherein the thermal storage portion comprises a plate-shaped first member, and has convex portions upon a surface of the first member that is opposite to the glass ingot.
