What does non-porous mean?
Porous means 'with holes'. So non-porous means 'without holes'
Definition of porous and non porous materials?
Porous means, containing pores ie, small or tiny hole, while non-porous means, without pores or holes.
Why must an eggshell be porous?
for oxidation
What is the root word of porous?
bones
What are porous metals?
Porous metal is a metal structure which has a number of holes.It is a new metal material which has characteristics of both porous structure and metal.
What is the difference between porous metals and metal foams?
When you intended to make a metal full of bubbles it is called 'foam'. When you wanted a solid metal and got bubbles in it, it is called 'porous'. So 'foam' is a good thing, 'porous' is a bad thing.
Are steel porous or non-porous?
Steel is typically considered non-porous due to its dense and solid structure. However, certain types of steel can have micro-pores or surface imperfections that make them slightly porous. Generally, stainless steel has better resistance to corrosion and is less porous than other types of steel.
Why wood is not attracted towards magnet?
Because it's not a metal and is a porous material.
What method is used to metal filtration devices and pre-lubricated porous bearings?
p/m possess
Is mirror surface non-porous?
Yes, a mirror surface is non-porous because it is typically made of glass or metal that does not have any open pores or holes through which liquid or air can pass. This non-porous nature is what allows mirrors to reflect light effectively.
Is sintering mandatory for powder metallurgy Why?
Sintering welds the metal powder grains together without melting them completely. This produces a solid but porous piece of metal.

How does rust being porous make rust very damaging and expensive?
If rust is porous that means that water can pass through it. This means that when the surface of a metal rusts it 'exposes' fresh metal underneath to water, meaning that that rusts too.In short, rust being porous means that all the metal is effected not just the surface. When Aluminium rusts it forms a hermetic (waterproof) layer which actually prevents further damage. That is why aluminum does not have to be as heavily protected as iron (which should be painted or galvanised to waterproof it)
What is pilling bedworth rule?
According to Pilling-Bedworth rule, if the volume of oxide layer formed is greater than the volume of the metal, the oxide layer is protective and non-porous. However if the oxide layer formed has volume lesser than that of the underlying metal then the oxide layer is porous and non-protective.
