CHAPTER 1: CLASSIFICATION OF MATERIALS

Density is a characteristic property of a material and can be a good way to identify an unknown sample. It is usually calculated from the mass and volume of a sample. density = mass / volume or d = m / V Example: A block of wood measures 2 cm by 1 cm by 5 cm. Its mass is 7.2 g. What is its density? The volume is 2 cm x 1 cm x 5 cm = 10 cm3 = 10 mL.

FURNACES AND REFRACTORIES

Creep at high temperature: Creep is a time dependent property, which determines the deformation in a given time and at a given temperature by a refractory material under stress. Volume stability, expansion, and shrinkage at high temperatures: The contraction or expansion of the refractories can take place during service life.
