What Is Ceramics And Glass

Engineers and product designers select glass or glass ceramics based on those properties.

What is ceramics and glass.

A well known example of a glass ceramic is the ceramic cooker hob which has been developed to have a thermal expansion coefficient close to zero. Use ceramic bakeware the same way you would glass. 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 is known to be a non crystalline material.

Ceramics and glass have many applications that require qualities such as hardness rigidity high resistance to heat corrosion etc. 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 glass ceramic cooktop is an extremely strong material that handles extreme temperature changes without breaking. Noncrystalline ceramics being glass tend to be formed from melts.

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. 9 the phase assemblage consists of spinel solid solution crystals dispersed throughout a continuous. Glass can be called as a type of ceramic. These glass ceramics can be made highly transparent with spinel crystals on the order of 10 50 nm in size fig.

The glass is shaped when either fully molten by casting or when in a state of toffee like viscosity by methods such as blowing into a mold. It s great for casseroles. Glass and ceramics are widely used for making household utensils. If later heat treatments cause this glass to become partly crystalline the resulting material is known as a glass ceramic widely used.

When to use it. Like glass ceramic bakeware is sensitive to extreme temperature changes so don t place that hot dish in a cold water bath. While glass ceramics often look and feel like glass they have different properties and there is a different manufacturing process involved. However it can break if you drop a hard object on it and can scratch especially when a granular object catches under a sliding pan on a stovetop.

We use a vast range of ceramic materials in the day to day life. Apart from making household materials glass and ceramics have found their place in many areas. Materials that are initially fabricated as glasses and perhaps shaped using glass moulding techniques and converted to a ceramic to enhance their properties are called glass ceramics.
