LITHIUM DISILICATE GLASS-CERAMIC COMPOSITIONS AND METHODS THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240026296 titled 'LITHIUM DISILICATE GLASS-CERAMIC COMPOSITIONS AND METHODS THEREOF
Simplified Explanation
The abstract describes a glass-ceramic composition that includes lithium disilicate as the main crystalline phase. The composition can also contain various other elements such as CaO, NaO, BO, and ZrO in specific weight percentages. Additionally, it can include SiO, AlO, PO, and LiO in specific weight percentages. The composition may also have a second crystalline phase, which can be wollastonite, apatite, cristobalite, β-quartz, lithiophosphate, or a combination thereof. The abstract also mentions methods of making and using the disclosed compositions.
- The glass-ceramic composition includes lithium disilicate as the primary crystalline phase.
- It can contain up to 10 wt% CaO, up to 5 wt% NaO, up to 10 wt% BO, and more than 0.5 wt% ZrO.
- The composition can also have 50-75 wt% SiO, 1-5 wt% AlO, 1-8 wt% PO, and 5-20 wt% LiO.
- It may include a second crystalline phase, such as wollastonite, apatite, cristobalite, β-quartz, lithiophosphate, or a combination thereof.
- The patent application covers methods of making and using the glass-ceramic compositions.
Potential Applications:
- Dental materials: The glass-ceramic composition could be used in dental restorations, such as crowns, bridges, and veneers, due to its biocompatibility and aesthetic properties.
- High-temperature applications: The composition's thermal stability and resistance to thermal shock make it suitable for use in high-temperature environments, such as in furnace linings or as heat-resistant coatings.
Problems Solved:
- Biocompatibility: The glass-ceramic composition addresses the need for dental materials that are biocompatible and safe for use in the human body.
- Thermal stability: The composition solves the problem of materials breaking or degrading under high temperatures, providing a stable and durable option for high-temperature applications.
Benefits:
- Aesthetic appeal: The glass-ceramic composition offers excellent aesthetic properties, making it an attractive choice for dental restorations that require natural-looking results.
- Versatility: The composition's ability to incorporate different crystalline phases allows for customization and tailoring of its properties to specific applications.
- Thermal resistance: The composition's resistance to thermal shock and high temperatures ensures its durability and reliability in demanding environments.
