Perhaps the most important consideration is a coating for the magnet, as typical neodymium disk magnets are not suitable for implantation. Magnets must be coated in an inert and biosafe material, so the body does not attack the magnet. Popular magnet coatings include implant grade silicone, parylene, titanium nitride, gold and rhodium. Disc ...
Nickel is both naturally abundant – it is the fifth most common element on earth – and widely used in industry and commercial goods. [2] Workplace nickel exposure is common in many industries, and the performance of normal work tasks can result in nickel skin levels sufficient to elicit dermatitis. [2]
Rhodium is a hard, silvery, durable metal that has a high reflectance. Rhodium metal does not normally form an oxide, even when heated. [25] Oxygen is absorbed from the atmosphere only at the melting point of rhodium, but is released on solidification. [26] Rhodium has both a higher melting point and lower density than platinum.

Usually parameters reproduce the value, and the template adds the SI unit or additional standard text. While the topic is technical, we can strive to make the result readable text, and even verbose. For example, this is why the template writes "(at 0 °C)". For this, you may want to experiment with parameter input too - or propose improvements.
Rhodite or rhodian gold is a naturally occurring alloy of gold and rhodium found in gold ore. Gold ore containing 34 to 43% rhodium was reported from Mexico and Colombia in 1825. [1] The alloy displays brittle tendencies and has a density of 15.5 - 16.8 g/cm 3. [2]
Rhodium(III) bromide refers to inorganic compounds of the formula RhBr 3 (H 2 O) n where n = 0 or approximately three. Both forms are brown solids. The hydrate is soluble in water and lower alcohols. It is used to prepare rhodium bromide complexes. [2] Rhodium bromides are similar to the chlorides, but have attracted little academic or ...
