Abstract
Official abstract text for this publication.
A glass ceramic material is disclosed that includes a residual glass, and a crystalline phase that includes a yoshiokaite phase. The yoshiokaite phase constitutes a main crystalline phase of the glass ceramic material. A method for making a glass ceramic material is also disclosed that includes heat treating frit glass to form the glass ceramic material, wherein the frit glass comprises: SiO2 from 15 mol % to 37 mol %; Al2O3 from 40 mol % to 47 mol %; and CaO from 20 mol % to 30 mol %.
First claim
Opening claim text (preview).
What is claimed is: 1. A glass ceramic material obtained from glass frits, the glass ceramic material comprising: an amorphous glass phase and a crystalline phase, wherein: the crystalline phase constitutes 80 wt. % or more of the glass ceramic material, and the crystalline phase comprises 80 wt. % or more of a yoshiokaite phase. 2. The glass ceramic material of claim 1 , wherein the crystalline phase comprises one or more of an anorthite phase, a gehlenite phase, a nepheline phase, and a cubic zirconia phase. 3. The glass ceramic material of claim 1 , wherein the crystalline phase comprises 90 wt. % or more of the yoshiokaite phase. 4. The glass ceramic material of claim 1 , wherein the yoshiokaite phase comprises yoshiokaite crystals having an average crystal size from greater than or equal to 100 nm to less than or equal to 160 nm. 5. The glass ceramic material of claim 1 , wherein the yoshiokaite phase comprises yoshiokaite crystals having an average crystal size from greater than or equal to 130 nm to less than or equal to 160 nm. 6. The glass ceramic material of claim 1 , wherein the crystalline phase constitutes 95 wt. % or more of the glass ceramic material. 7. The glass ceramic material of claim 1 , wherein the glass ceramic material has a density of greater than or equal to 2.0 g/cm 3 . 8. The glass ceramic material of claim 1 , wherein the glass ceramic material has a density of greater than or equal to 2.0 g/cm 3 to less than or equal to 3.0 g/cm 3 . 9. An electronic device, comprising: electrical components; and a glass ceramic material component comprising the glass ceramic material of claim 1 electrically connected to the electrical components. 10. The glass ceramic material of claim 1 , wherein the crystalline phase comprises 85 wt. % or more of the yoshiokaite phase.
