What does antimony mean?
1 : stibnite.
2 : a trivalent and pentavalent metalloid element with atomic number 51 that commonly occurs in a brittle, metallic, silvery white crystalline form and that is used especially in alloys, semiconductors, and flame-retardant substances — see Chemical Elements Table..
What is antimony used in?
A lead-antimony alloy is used in batteries. Other uses of antimony alloys include type metal (in printing presses), bullets and cable sheathing. Antimony compounds are used to make flame-retardant materials, paints, enamels, glass and pottery. Antimony and many of its compounds are toxic.
Is antimony found in the human body?
The amount of antimony that will enter your blood from your lungs is not known. Antimony in the blood will be distributed throughout the body, with the highest amounts in the blood, spleen, liver, and kidneys. Antimony will leave your body in feces and urine over several weeks.
What are the symptoms of heavy metals in the body?
What are the symptoms of heavy metal poisoning?diarrhea.nausea.abdominal pain.vomiting.shortness of breath.tingling in your hands and feet.chills.weakness.
Is antimony a metal or nonmetal?
Pure antimony metal is silver gray/white and brittle. Although actually a metal, like germanium and tellurium (of which more in forthcoming articles), antimony is also termed a metalloid. (A metalloid displays the characteristics of both a metal and a nonmetal.)
How many bullets do you get from a pound of lead?
If a pound of lead is 7,000 grains then you could only make 30 230gr bullets. A pound of lead at midwayusa runs over 30 bucks.
What is antimony in the Bible?
Antimony is a chemical element that can be found on the periodic table as the atomic symbol Sb. Knowledge of it dates back to biblical times, when antimony minerals were used in products such as cosmetics. … Antimony is used for a variety of products, such as flame-retardants and lead batteries.
How much antimony is lethal?
The lethal oral dose of metallic antimony in rats is 100 mg/kg of body weight; the trivalent and pentavalent oxides are less toxic, with LD50 in rats ranging from 3200–4000 mg/kg of body weight. The recommended workplace limit (ACGIH TLV-TWA) for antimony is 0.5 mg/m3 as an 8-hour time-weighted average.
Where is Antimony most commonly found?
Antimony is sometimes found in pure form. It is also obtained from the mineral stibnite (antimony sulfide) and commonly is a by-product of lead-zinc-silver mining. Other antimony-bearing minerals include sibiconite, tetrahedrite and ullmannite. It is mined in China, Bolivia, South Africa and Mexico.
Can antimony kill you?
Exposure to relatively high concentrations of antimony (9 mg/m3 of air) for a longer period of time can cause irritation of the eyes, skin and lungs. As the exposure continues more serious health effects may occur, such as lung diseases, heart problems, diarrhea, severe vomiting and stomach ulcers.
Is antimony a heavy metal?
Other examples include manganese, chromium, cobalt, nickel, copper, zinc, silver, antimony and thallium. Heavy metals are found naturally in the earth. … Some elements otherwise regarded as toxic heavy metals are essential, in small quantities, for human health.
What foods contain antimony?

Why is W The symbol for tungsten?
Tungsten comes from a Swedish term, tung sten, that means “heavy stone.” Tungsten’s chemical symbol is a W, which may seem weird since there isn’t a W in the word. The W actually comes from the element’s other name, wolfram. The name wolfram comes from the mineral the element was discovered in, wolframite.
What are paper patched bullets?
Paper-patched bullets Patching is the hand process of applying paper jackets. The projectile is cast to a diameter that is usually that of the bore and needs to be brought up to groove diameter by a uniform number of paper wrappings.
Are wheel weights good for casting bullets?
Wheel weights can be found anyplace that sells tires and are perhaps the most available and inexpensive material for bullet casting. They rank 9-13 on the Brinell scale and about six on the Saeco hardness tester. That’s hard enough to work for most cast pistol bullets and for low-velocity rifle bullets.
Is antimony toxic to the body?
Antimony toxicity occurs either due to occupational exposure or during therapy. Occupational exposure may cause respiratory irritation, pneumoconiosis, antimony spots on the skin and gastrointestinal symptoms. In addition antimony trioxide is possibly carcinogenic to humans.
Why is antimony used in bullets?
There are several lead alloys used in bullet casting. They utilize varying amounts of tin and antimony, as well as trace amounts of other metals, in order to harden the bullet and to make it cast better. High ratios of antimony will harden lead considerably, but at the expense of brittleness.
Is antimony shiny or dull?
Antimony is a lustrous, silvery, bluish white solid that is very brittle and has a flaky texture. It occurs chiefly as the gray sulfide mineral stibnite (Sb2S3).
