1.
2. Amorphous, Hard, Brittle
Transparent/ Translucent
No definite melting point or
structure
Produced by fusion of silica,
lime, potash or soda
Super cooled liquid
3. Glass making nowadays is a modern and hi-tech industry. New chemical
compositions and new development techniques have been initially
investigated at small-scale. There have been many advancements in glass
technology.
Some of the advanced technologically important glass are:
5. Glass/ glazing whose light transmission properties are altered when voltage, light,
or heat is applied. Generally, glass changes its property from transparent
to translucent and vice versa.
Electrochromic device
Photochromic device
Thermochromics device
Suspended particles device
Polymer dispersed crystal liquid device
Devices related to technology
used in Smart glass
6. Bioactive glasses are those that can provoke a specific beneficial biological response
when implanted
It forms an apatite-like layer on its surface after incubation in
Simulated Body Fluid (SBF)
Applications
Bone regeneration
Periodontics
Dentistry implant
Hemostatic agent
Angiogenesis
Nano carrier
Co-drug delivery
8. GORILLA GLASS
Made from Alkali-
Aluminosilicate
Resistant glasses
Strong & Thin
Alternative of
plastics used in
devices
High flexibility
Flexibility
9. NANO CHANNEL GLASS MATERIALS
Alternate method for
fabricating nanostructures
Complex glass structures containing
large numbers of parallel hollow
channels
High density of uniform channels with
diameters from 15 micrometers to 15
nanometers
Hollow channels are arranged in
geometric arrays with packing
densities as great as 1011 channels/cm2.
Material for
chromatographic columns,
unidirectional conductors,
Microchannel plate and
nonlinear optical devices
Masks for semiconductor
development, including ion
implantation, optical
lithography, and reactive ion
10. Hydrophilic and
photocatalytic coating on
window that is activated
using UV rays present in
daylight
Photocatalytic action
breaks down organic dirt
that lands on the surface of
your windows, preventing
anything from sticking to
the glass.
Working
It is a specific
type
of glass with a
surface that
keeps itself free
of dirt and
grime.
12. GLASS POLYMER
Glass Polymer is an attractive and versatile material that can take
packaging to another level of appearance.
Moldable composite
material
Comprises short
glass fibers in a
matrix of a polymer
material
Used to manufacture
wide range of structural
components
by injection or compressi
on molding
Ideal glass Alternative
that offers design
flexibility, chemical,
durability, and
chemical and shatter
resistance
CHARACTERISTICS
13. Polycrystalline
material
Production: Controlled
crystallization of base glass
Amorphous phase
& crystalline phases
Share properties with
both glasses and ceramics.
Key to a glass-ceramic material is controlling
the nucleation and growth of crystals in the base glass
