Title:
TEMPERATURE DETECTION MATERIAL, TEMPERATURE DETECTION METHOD, AND METHOD OF MANUFACTURING NOBLE METAL PRODUCT
Document Type and Number:
Japanese Patent JP2001228031
Kind Code:
A
Abstract:
To provide a temperature detection material, temperature detection method, and method of manufacturing noble metal products.
The temperature detection material consists of two or more kinds of compacts selected from among compacts forming glass power with a known softening point and melting point or compacts forming mixed glass powder mixed a glass powder having a known softening point and melting point with materials with high fire resistance, such as SiO2, ZrO and alumina powder. Each compact is formed so that the compact has different softening temperature and melting temperature respectively and softens to be almost spheral at each temperature.
