Corrosion resistance of nickel alloys in molten sodium

The corrosion resistance of 11 nickel-based compositions to molten sodium hydroxide at 1500 degrees and 1700 degrees was studied in order to find a container material for the caustic at these temperatures. Although, in caustic, pure nickel is corrosion resistant (suffering only thermaal-gradient mass transfer), it is structurally weak.

Acid Resistant Cement, Acid Proof Cement, Silie …

Sulphur cements are a single component,easy to use acid proof cement. Unlike other cements, it is applied in molten condition it does not require curing time. Hence they are more suited for maintenance jobs. They are extensively used in electrical insulators for fixing metallic parts on ceramics. They are also used in acid resistant masonry.

Metals and Alloys timeline | Timetoast timelines

Due to nickel’s resistance to corrosion and its strength, it is used in many alloys such as stainless steel. It was named for various black minerals such as pyrolusite from Greece By the mid-18th century, Swedish chemist Carl Wilhelm Scheele used pyrolusite to produce chlorine. Now, sodium is produced on an industrial scale through

How and why alloying elements are added to aluminum

Chromium (Cr) – Chromium is added to aluminum to control grain structure, to prevent grain growth in aluminum-magnesium alloys, and to prevent recrystallization in aluminum-magnesium-silicon or aluminum-magnesium-zinc alloys during heat treatment. Chromium will also reduce stress corrosion susceptibility and improves toughness.
