For the range from 200 to 4000 C, the average coefficients of expansion of the samples of cemented tungsten carbide containing about 13 percent of cobalt are 15 percent greater than the coefficient of expansion of the cemented tungsten carbide containing about 6 percent of cobalt.
Refractory metals are also typically characterized by a low coefficient of thermal expansion and relatively high density. The fact that molybdenum belongs to the same group as tungsten in the periodic table means that it has a similar atomic structure and chemical properties.
The coefficient of thermal expansion of neat cement paste ranges from around 11 × 10 ?6 /°C to more than 20 × 10 ?6 /°C. Natural rocks used for aggregates exhibit a considerable range of thermal expansion coefficients, related generally to silica content (Table ), but rarely exceed about 12 × 10 ?6 /°C and can be as low as 4 × 10 ?6 /°C. The overall thermal expansion coefficient of concrete will be substantially influenced by the type of aggregate present, because of the
