Abstract
A method for producing a molten glass conveying equipment element. The molten glass conveying equipment element has a conduit structure for molten glass containing at least one conduit comprising platinum or a platinum alloy, a first ceramic structure provided around the conduit and a second ceramic structure located around the first ceramic structure. The method includes filling a gap between the conduit and the second ceramic structure with a slurry body, and sintering the slurry body at a temperature of 1,300 to 1,550° C., thereby forming the first ceramic structure. The slurry body is prepared by blending specific first particles, specific second particles and specific third particles with specific mass ratios.
