Nickel is widely distributed in nature, forming about 0.008% of the earth's crust. The core of the earth contains 8.5% nickel, deep-sea nodules 1.5%; meteorites have been found to contain 5–50% nickel (5). The natural background levels of nickel in water are relatively low, in open ocean water 0.228–

4.4 Some common methods of sampling, listed by source, are as follows: 4.5 Billets, Blooms, and Hot-Rolled Products—Disks are usually cut from these products near the end. Samples cut too close to the end, however, may have false structures because of fish-tailing. Disks from large blooms are sometimes cut into smaller pieces for ease in ...

Nickel is a silvery white, naturally occurring metallic element with a light golden tinge. There are two main types of nickel deposits - laterite and sulphide – each requiring a different extraction technique. Stainless steel. Nickel sulphide and laterite ore are used to make nickel metal, predominantly for the production of stainless steel.

The CrxNi1-x materials were also prepared by mechanical milling. Utilizing a ball-to-powder mass ratio of 20 : 1 and selecting the proper alloy compositions we were able to obtain nanocrystalline CrxNi1-x particles. Thermal demagnetization in the vicinity of the Curie temperature of the nanoparticles was studied using a modified TGA-SDTA method.
