Günter Reich,Cornelia von Wallmodencause of its high density (. = 19.1 g/cm.) and in some cases its structural properties. Because depleted uranium is a by-product of enriched nuclear fuel, it is less expensive than any other high-density material. Tungsten, with a density of 19.3 g/cm., not only has a higher raw material cost but al

Inge Seiffge-Krenkeccelerating their corrosion. In 1891, the possibility that microorganisms might exert an influence on the corrosion of metals was mentioned by Garrett.. He postulated that the increase in the corrosive action of lead could be due to the ammonia, nitrites, and nitrates produced by bacterial action.

Joachim Walter,Hubertus Adamuch is not the case, as can be attested to by certain optical glasses that are readily stained in the atmosphere (e.g., dense flints and barium crowns) or etched by mild acid action, the effects being readily observed with the naked eye. Most glasses, including the “chemically resistant” glasses, wi

Failures of this type lead not only to a deterioration of the mechanical properties of structural material, but
