Ceramics | Encyclopedia

2019-4-13 · Ceramics tend to have high, well-defined melting points, while glasses tend to soften over a range of temperatures before becoming liquids. In addition, most ceramics are opaque to visible light, and glasses tend to be translucent. Glass ceramics have a structure that consists of many tiny crystalline regions within a noncrystalline matrix.

PROPERTIES AND CHARACTERISTICS OF GRAPHITE

2015-5-22 · 4 PROPERTIES AND CHARACTERISTICS OF GRAPHITE POCO GRAPHITE, INC. STRUCTURE Thermodynamically, graphite at atmospheric pressure is the more stable form of carbon. Diamond is trans-formed to graphite above 1500°C (Figure 1-4). The structure of graphite consists of a succession of layers parallel to the basal plane of hexagonally linked carbon atoms.

Why is the melting point of carbon so much higher …

Why does graphite have a higher melting point than diamond? The melting point of carbon is much higher than the silicon because of its covalent nature, rather than the more metallic character of the silicon.

Tungsten - Element information, properties and uses

Tungsten carbide is immensely hard and is very important to the metal-working, mining and petroleum industries. It is made by mixing tungsten powder and carbon powder and heating to 2200°C.
