Gases like oxygen or hydrogen are frequently diffused into liquids like water or solvents using sintered metal gas diffusion stones, which are porous materials. The porous structure of these stones allows gases to easily diffuse into the liquid, increasing the surface area of contact between the two phases, and facilitating a more efficient transfer of gas into the liquid.
Water treatment, chemical reactions, and the mass transfer of gases and liquids are just a few of the uses for sintered metal gas diffusion stones.

Versatility: Metal diffusion stones have a wide range of uses, including gas-liquid mass transfer, chemical processes, and water purification.
Durability: Because of their toughness and capacity to survive adverse conditions, these stones are suited for usage in industrial settings.
Applications
Water treatment: These stones are commonly used in water treatment processes, such as aeration and ozonation, to increase the dissolved oxygen levels in water and improve its quality.
Biotechnology: Gas diffusion stones are used in bioreactors for cell culture and fermentation processes, where they are used to provide oxygen to support the growth of microbes and other cells.
Chemical processing: These stones are used in chemical processing applications, such as gas-liquid reactions, where they facilitate the transfer of gases into liquids to promote chemical reactions.
Food and beverage: Gas diffusion stones are used in the food and beverage industry for carbonation and oxygenation of drinks, as well as for yeast propagation in brewing.
Pharmaceutical industry: These stones are used in the pharmaceutical industry for a variety of applications, including cell culture, fermentation, and purification processes.
Pularin: Foot ball shaped 60 atoms of carbon at edges is layed in pularin.Pularin atoms are arranged in ball. Each atom is called Bucky balls and tubes are called Bucky tubes or Nano tubes.Each nano tube is 1 to 7 nm diameter i.e 1nm=50000 part of a hair sting. where? 1)mangampet ,cuddapah dist.Ap,India.app 800 ppm(parts prer million)info given by stanford University. Cost: 150 times costlier than gold. 10 grams pularin $23000 to $45000 also info given by Bucky-USA website. Special uses if this becomes common: 1)Pularin coting on aeroplanes withstands from thunders ,rains ,Flashes etc. 2)Bullet proof ackets 3)curing cancer etc.

We are glad to propose 500 MT of stain less steel mill scale. Mill scale is formed on the outer surfaces during by the hot rolling lamination of stainless-steel products. At a visual inspection the material is a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in colour, but it also contains considerable alloying elements such as chromium and nickel. The recovery ratio after melting in furnace for the most valuable alloy elements is: - Ni: 3.5 - 4.5% - Cr: 6-8% From the chemical and physical analysis performed on the scrap, and according to the European environmental rules, the material has been classified as a special non dangerous waste, listed in green list. In particular the mill scale can be classified as follows: Waste code: 10 02 10 The material is stored on cemented flooring, and it can be loaded loose in tipper trucks or containers. Chemical analysis of the material is available on request.

Metal tin is mainly used in the manufacture of alloys. Tin and sulfur compounds - tin sulfide, which is similar in color to gold, is commonly used as a gold pigment. Tin's modern application is as a solder for the electronics industry. Used in various purities and alloys (often with lead or indium), tin solders have a low melting point, which makes them suitable for bonding materials.
