Title:
Insulation layer forming material, insulation layer forming paste
Document Type and Number:
Japanese Patent JP6293735
Kind Code:
B2
Abstract:
An insulating layer forming material and an insulating layer forming paste capable of forming an insulating layer on a metallic substrate without the filler and glass reacting or warpage occurring even when repeatedly fired at 850° C. or higher are provided. The insulating layer forming material containing a lead-free glass composition and an α-quartz filler contains 17.0-40.0 wt. % of the α-quartz filler and 60.0-83.0 wt. % of the lead-free glass composition. The α-quartz filler has an average particle diameter (D50) of 1.0-3.5 μm and a specific surface area of 2.5-6.5 m2/g. The lead-free glass composition includes no B2O3 and comprises a composition, in mol %, of 40.0-60.0% SiO2, 0.5-10.0% Al2O3, 20.0-45.0% MgO+CaO+SrO+BaO, 5.0-23.0% ZnO, and 0-10.0% Li2O+Na2O+K2O.
