Abstract
A method includes placing a material including a glass precursor material in contact with a second material and annealing the glass precursor material to form a glass composition in contact with the second material. In an embodiment, annealing is performed at a single temperature. In another embodiment, annealing is performed at a temperature in a range of 750° C. to 1000° C. In a particular embodiment, the glass composition includes a crystalline fraction of at least 30%.
Claims20
A method comprising:
- placing a first material in contact with a second material, wherein the first material comprises a glass precursor material including SiO2, Al2O3, and BaO, and the second material comprises a metal, a metal alloy, a metallic compound, a ceramic material, or any combination thereof;
- and
- annealing the first material to form a glass composition in contact with the second material, wherein annealing is performed at a single temperature, and the glass composition has a crystalline fraction of at least 30 vol %.
A method comprising:
- placing a first material in contact with a second material, wherein the first material comprises a glass precursor material including SiO2, Al2O3, and BaO, and the second material comprises a metal, a metal alloy, a metallic compound, a ceramic material, or any combination thereof;
- and
- annealing the glass precursor material to form a glass composition in contact with the second material, wherein annealing is performed at a single temperature in a range of 750° C. to 1000° C.
A method comprising:
- placing a first material in contact with a second material, wherein the first material comprises a glass precursor including SiO2, Al2O3, and BaO, and the second material comprises a metal, a metal alloy, a metallic compound, a ceramic material, or any combination thereof;
- and
- annealing the first material to form a glass composition in contact with the second material, wherein annealing includes:
- a first portion is performed at a first temperature for a first time;
- and
- a second portion is performed at a second temperature for a second time,
- wherein:
- the first temperature is different from the second temperature;
- and
- the first time, the second time, or each of the first and second times is at least 9 hours.
