Title:
SETTER FOR HEAT TREATMENT OF GLASS SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2008/007621
Kind Code:
A1
Abstract:
Disclosed is a setter for a heat treatment of a glass substrate, which is hardly deformed even when repeatedly used within a temperature range of a heat treatment for a glass substrate. Specifically disclosed is a setter for a heat treatment of a glass substrate, which is composed of a ceramic sintered body. This setter for a heat treatment of a glass substrate is characterized in that the ceramic sintered body has a water absorption of 0-0.14% by mass after a heat treatment at 600˚C. Also specifically disclosed is a method for producing a setter for a heat treatment of a glass substrate, wherein a primitive plate is formed by sintering a raw material powder. This method for producing a setter for a heat treatment of a glass substrate is characterized in that the raw material powder contains a crystalline powder and/or a crystallized glass powder and a frit powder, and the difference of average thermal expansion coefficient at 30-600˚C between the crystalline powder or crystallized glass powder and the frit powder is not more than 40 x 10-7 /K.
