Title:
TEMPERATURE-DETECTING ELEMENT
Document Type and Number:
Japanese Patent JP3510978
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To provide a new temperature-detecting element which can highly accurately detect temperatures near 800-1000°C.
SOLUTION: The temperature-detecting element is formed of a molding including 20-80 vol.% of a lithium silicate-based glass ceramic containing 5-30 wt.% of Li2O and 20-80 vol.% of a ceramic filler of forsterite, quartz or the like. The size change of the element because of a shrinkage incident to baking after kept in an unknown temperature is measured, from which an unknown temperature of 800-1000°C can be detected. For example, a temperature inside a ceramics or metallic container or sheath at the time of baking the glass ceramics can be measured accurately.
