Product Overview

Fluoroaluminosilicate glass is a high-performance specialty glass, primarily composed of fluorine (F), aluminum (Al), silicon (Si), and oxygen (O). It is manufactured through a special formula and high-temperature melting process. Its unique chemical composition endows it with excellent optical, mechanical, and chemical properties, widely used in dental materials, optical devices, electronic packaging, and high-temperature industrial applications.

Features

High refractive index and optical uniformity

Refraction range: 1.48-1.52 ( customizable ), high matching with common resin materials (such as UDMA) to enhance the light transmission and optical properties of composites.

Low dispersion characteristics, reducing chromatic aberration in optical components, suitable for high-precision optical lenses and coated substrates.

Chemical Stability and Corrosion Resistance

High resistance to acid and alkali erosion, especially excels in fluorine-containing environments. Suitable for chemical equipment viewports and corrosion-resistant coatings.

The introduction of fluorine enhances the chemical stability of glass, reducing ion leaching.

Mechanical properties and thermal stability

Hardness reaches 6-7 Mohs, offering better wear resistance than ordinary glass, thereby extending the service life of products.

Softening Temperature: 800-1000°C, suitable for sealing, encapsulation, and structural components in high-temperature environments.

Non-toxic, fluoride-releasing, with cavity-preventing properties, widely used in dental resin fillings and glass ionomer cements.

Typical Applications

Dental Materials

Resin-based composite materials: Serve as a substitute for beijing glass powder, when used in conjunction with UDMA resin, enhance the strength, transparency, and wear resistance of the filling material.

Glass Ionomer Cement: with poly-Propionic acidReactive formation of repair material for dental caries filling and crown bonding.

Optics field

Optical Lenses and Prisms: High refractive index and low dispersion properties are suitable for camera lenses, telescopes, and other precision optical components.

Coated Substrate: High surface flatness, suitable for AR (anti-reflective) and IR (infrared) coatings, enhancing the performance of optical devices.

Electronic Packaging

Chip Packaging: With high-temperature and moisture resistance, it can serve as semiconductor packaging material, protecting chips from environmental erosion.

Sensor Window: Maintains stability in harsh environments (such as high temperatures), suitable for industrial sensors and automotive electronics.

High-Temperature Industrial

High-Temperature Sight Glass: Withstanding temperatures up to 1000°C, used as observation windows for boilers, furnaces, and other equipment.

Sealing Materials: Used for metal or ceramic sealing in vacuum equipment and high-temperature pipelines.
