Definitions
- the present invention relates to glass, a solid electrolyte containing the glass, and a binder for binding.
- a glass material can be sintered at a lower temperature than a ceramic material made of crystals. Utilizing this property, glass powder has been used as a binder for binding powder materials such as ceramic powder and electrode powder for low temperature co-fired ceramic multilayer substrates. By using low-temperature sinterable glass powder as a binder for binding, it is possible to bind a powder material that is easily modified by heat while suppressing the modification.
- Glass containing lithium is expected to be used as a material for forming a dielectric layer (insulator layer) in a high-density circuit board by mixing it with, for example, functional ceramic powder. It is also expected to be used as a material for forming a conductive layer by mixing with a conductive powder such as metal.
- lithium-containing glass has high ionic conductivity, it is expected as a material for a solid electrolyte.
- Patent Documents 1 and 2 The use of glass containing _ ⁇ 2 ⁇ the Tokoro quantified as an electrolyte are disclosed.
- Patent Document 1 Japanese Patent Laid-Open No. 2 0 1 5 -6 3 4 4 7
- Patent Document 2 Japanese Patent Publication No. 3-6 1 2 8 6
