Sintered glass is a glass mesh used for filtration. It can be used instead of filter paper, and in fact is preferable to filter paper. Its other advantage is that it is permanent so you can get various different pieces of glassware with sintered glass in it e.g. an enclosed filter suitable for filtration under nitrogen.
As for the porosity.... Porosity of sintered glass is labelled by integers from 0-5 (viz. 0, 1, 2, 3, 4, 5) where 0 has a pore size of 160-250 micrometres and is considered course filtration, that is fluid will pass through it quickly and some finer solids will pass through. Whereas, porosity 5 has a pore size of 4-10 micrometers so even ultrafine solids will not pass through and liquids will drop through.
I hope this is clear, makes sense and is helpful.
Sintered glass crucible is a glass mesh used for filteration. It can be used instead of filter paper, and in fact it is preferrable to filter paper. Sintered glass crucible must be cleaned then dried to constant weig befoe it can be used to filter out precipitates such as silver chloride.
yes.... it is an answer for porosity....
Baljet reagent freshly prepared (95 ml 1% picric acid + 5 ml 10% NaOH) mixed immediately before use and filtered through a sintered glass funnel.
Obviously enough.
physical! :)
The pore size is the average 100 micrometers.

No, glass is not porous
A sinterd funnel is simply a funnel with a built in filter. The filter is sintered, I think that this means that small particles are compressed together (and heated ?) to form a single piece of material with many small holes. The sintered funnels I use are made of glass, a link to some images is below (not mine). http://curlyarrow.blogspot.com/2008/01/how-to-clean-your-sintered-funnel.html I have also used sintered polyethylene and sintered stainless steel for filtering.
Because of the gravity of the earth....
To avoid contamination, especially in chemical analysis.
big particles=low porosity small particles=high porosity
Ang kahulugan ng "porosity" sa Tagalog ay "papak" o "bukas-bukas." Ito ay tumutukoy sa dami o kahabaan ng mga butas o espasyo na makikita sa isang bagay tulad ng lupa o kahoy.
Porosity is the formation of bubbles in the weld.
how do we calculate porosity of ceramic?
poorly sorted = low porosity well sorted = high porosity
