In these days, it is interested that amorphous materials are known to have special properties as catalyst, corrosion resistance, properties as semiconductor and mechanical properties that have an difficulty of obtaining from crystalline solids. Amorphous meaterials is not yet well-known, for the study of its structure is difficult in comparison with it of crystalline materials.
As amorphous materials are in the nonequilibrium state, they have the weak point of the nonduration of structure. But it is expected that the future uses are various because of special properties by only amorphous materials.
For last ten years, according as technique of preparation of amorphous materials was developed, they had became succesively prepared by the method of solidification by rapid cooling from fused state. Amorphous materials which have strength equal to piano wire, better corrosion resistance than stainless steel and properties for light memory are now known.
Here, the properties, preparations and uses of amorphous materials were reviewed.
