Red Mercury is a discredited substance, often considered a hoax, and it does not exist as a legitimate or scientifically recognized material. It has been associated with various myths and scams, particularly in the context of nuclear materials or magical properties.
If you are looking for substances related to mercury, such as Mercury(II) oxide (a red powder), it is available from certain suppliers, but it is not the mythical "red mercury" and should be handled with caution due to its toxicity. However, as of the last update, Mateck's Mercury(II) oxide was out of stock.
For any legitimate scientific or industrial needs, you should consult reputable suppliers like Sigma-Aldrich, which offers various mercury-related compounds for research purposes. However, they do not list "red mercury" as it is not a real substance.
Important Note: Be cautious of scams and misinformation surrounding "red mercury." It is not a real substance and has been used in fraudulent schemes.
