OST 88.00.021.228-76. Sheets of fused tantalum.
Are you interested in OST 88.00.0211.228−75 «Sheets of fused tantalum» from the supplier company AvecGlob? Here you will find the necessary information on this topic.
Application area
Sheets of fused tantalum are obtained from glazing beads, which, in turn, are made from sintered tantalum powder, recovered in a medium of pure carbon. A variety of fused sheets: a thickness of at least 5 mm, with a width of 500… 800 mm. The length of the sheet is usually set according to the individual order of the consumer, but usually ranges from 500 to 2000 mm. Fused tantalum, which meets the requirements of OST 88.00.0211.228−75, must be not less than 99.9% of chemical purity.
Application of fused tantalum sheet
Basically, the operational properties of fused tantalum — inertness to virtually all acids, high corrosion resistance, strength, ductility, toughness and thermal conductivity. The sheets of fused tantalum are characterized by ductility at room temperatures, so they can be used to manufacture sheet-shaped parts that are different in configuration, including complex configurations.
In medicine, sheets of fused tantalum are used to make protective screens for X-ray equipment, as well as surgical implants.
Another important application of sheet steel from fused tantalum is for electronic components. Due to its absorption properties, tantalum is an excellent getter for residual gases in evacuation pipes.
