Oct 29, 2017 Interconnected porosity is a network of pores on a coating surface. There are two kinds of porosity - open and closed: Open porosity, also known as interconnected porosity, is the ratio of the volume of void space within the material that is accessible from the exterior to the bulk volume.

Bulk density/ open porosity. The bulk density (BD) is the amount of refractory material within a volume (kg/m3). An increase in bulk density of a given refractory increases its volume stability, heat capacity and resistance to slag penetration. The apparent porosity or open porosity (oPo) is the volume of the open pores, into which a liquid can ...

Abstract: The effect of open porosity of Y 2 O 3 ceramic on the apparent contact angle and interaction between molten Ti47Al alloy and Y 2 O 3 ceramic substrates under pure Ar was investigated by using a sessile drop method at 1600 C. As the open porosity increased from 9.6% to 30.3%, the spreading rate of molten Ti47Al alloys on Y 2 O 3 ceramic substrates reduced from 2.3 to 1.1/s ...

One method in which porosity is determined is by laboratory measurements of Core Samples brought to the surface during drilling. Measurement of porosity in the laboratory is part of Routine Core Analysis, sometimes referred to as PKS Analysis (porosity, permeability, and saturation analysis).. Core samples are rock samples that are cut from the reservoir formation using specialized Coring Bits.
