Usually they are metal oxides that is compounds of metallic elements and oxygen but many ceramics.

Structure of glass and ceramics.

When the glass was overheated small crystals formed in the amorphous material that prevented cracks from propagating through the glass. Glass ceramics are polycrystalline materials produced through controlled crystallization of base glass. Silicate glasses are the most widely used glasses. We use a vast range of ceramic materials in the day to day life.

A glass is a material that has hardened and become rigid without crystallising making it amorphous. This sio 2 tetrahedral unit is also incorporated into chains and sheets clays forming different ceramics. The first step toward glass ceramics involves conventional techniques for preparing a glass. Amorphous structure means that atoms are not organized according to a well ordered repeating arrangement as in crystals.

Ceramic composition and properties atomic and molecular nature of ceramic materials and their resulting characteristics and performance in industrial applications. 9 the phase assemblage consists of spinel solid solution crystals dispersed throughout a continuous. An accidental overheating of a glass furnace led to the discovery of materials known as glass ceramics. Ceramics and glass have many applications that require qualities such as hardness rigidity high resistance to heat corrosion etc.

Glass ceramics are made of small grains surrounded by a glassy phase and have properties in between those of glass and ceramics. The key difference between glass and ceramic is that ceramics have crystalline or semi crystalline or non crystalline atomic structure whereas the atomic structure of glass is non crystalline. In our previous study we investigate the crystallization mechanism structure and properties of glass ceramics from modified molten blast furnace slag with different cao sio 2 and al 2 o 3 na 2 o 17 18. For glass ceramics from molten bf slag crystallization control is always difficult due to the high content of cao in bf slag.

Glass ceramic materials share many properties with both glasses and ceramics glass ceramics have an amorphous phase and one or more crystalline phases and are produced by a so called controlled crystallization in contrast to a spontaneous crystallization which is usually not wanted in. Glass ceramics based on spinel compositions ranging from gahnite znal 2 o 4 toward spinel mgal 2 o 4 can be crystallized using zro 2 and or tio 2 as nucleating agents. The addition of glass network modifiers that can alter the glass or glass ceramic reactivity incorporation of specific biomolecules into porous structures surface functionalization etc are only a few examples of major strategies to expand the clinical applications of bioglasses. Pure silica can be made to exist as a glass and is called fused silica.

Properties of glass ceramics glass ceramics can range from highly crystalline to containing a more substantial glassy phase. Industrial ceramics are commonly understood to be all industrially used materials that are inorganic nonmetallic solids.
