Document Type and Number:
Japanese Patent JP2016104684
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a glass power and a composite powder suitable for a top plate for cookers having a picture layer or the like, being softened and flowed at low temperature, low in thermal expansion coefficient and high in water resistance and acid resistance.SOLUTION: There is provided a glass powder containing, by mol%, SiO:48 to 75%, BO:5 to 23%, AlO:5 to 25%, LiO:5 to 30%, ZnO:0 to 25% as a glass composition with a mole ratio SiO/BOof 3.23 or more, where β-quartz solid solution is deposited as a main crystal by burning under a condition at 700°C for 10 minutes, and having thermal expansion coefficient of 25×10/°C or less.SELECTED DRAWING: Figure 1
