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.
Porosity 4 sintered glass typically has pore sizes ranging from 4 to 16 micrometers, with an average pore size of around 8 micrometers. The pore size distribution can vary depending on the specific manufacturing process and conditions used to produce the sintered glass material.
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....
To carry out a hair porosity test, take a few clean strands of hair and place them in a bowl of water. If the hair sinks quickly, it has high porosity. If it floats, it has low porosity. If it floats in the middle, it has normal porosity. This test helps determine how well your hair absorbs and retains moisture.
To conduct a porosity hair test, take a strand of hair (clean and dry) and place it in a bowl of water. If the hair sinks quickly, it likely has high porosity. If it floats, it might have low porosity. If the hair floats in the middle of the water, it is considered to have normal porosity.

The pore size is the average 100 micrometers.
Sintered glass crucibles typically use a type of filter paper known as "sintered glass filter discs" or "sintered glass filters." These filters are made from finely powdered glass that is sintered to form a porous structure, allowing for the filtration of fine particles while maintaining chemical resistance. They are commonly used in laboratory applications for filtration, drying, and other processes where durability and purity are essential.

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.
No, glass is not porous
Because of the gravity of the earth....

To avoid contamination, especially in chemical analysis.
Sintered bronze is a material produced by compacting and heating bronze powder, which typically consists of copper and tin, without melting it. This process, known as sintering, allows the particles to fuse and form a solid structure while retaining the porous nature of the material. Sintered bronze is often used in applications such as bearings, bushings, and filters due to its excellent wear resistance, low friction properties, and ability to withstand high temperatures. Its porosity also allows for the retention of lubricants, enhancing its performance in various mechanical applications.
big particles=low porosity small particles=high porosity
