There are no refractory materials that can contain molten tungsten; consequently powder metallurgical routes are invariably used in the initial processing of tungsten. Thus, tungsten (and any alloying components) in powder form are generally hydrostatically pressed into …

Evaluating Refractory Properties - Resco Products

For refractories based on alumina materials, density generally increases with alumina content. Apparent porosity is a measurement of the volume of the open pores within a refractory. Since infiltrating materials from the process migrate through the pore structure, apparent porosity is a property to evaluate when selecting a refractory.
