![]() ![]() (APF = 50) Any air-purifying, full-facepiece respirator with an N100, R100, or P100 filter. (APF = 25) Any powered, air-purifying respirator with a high-efficiency particulate filter. (APF = 25) Any supplied-air respirator operated in a continuous-flow mode The following filters may also be used: N99, R99, P99, N100, R100, P100.Ĭlick here for information on selection of N, R, or P filters. If you are unsure what these import costs will be please check with your country's customs office.(APF = 10) Any particulate respirator equipped with an N95, R95, or P95 filter (including N95, R95, and P95 filtering facepieces) except quarter-mask respirators. If you refuse our package because of this extra cost we will take it back and will refund your order in full once received minus the cost of the return shipping. We have nothing to do with this and cannot pay it for you. International shipping is via DHL, FedEx, or USPS international express and costs $45 for shipments up to a pound (9 one ounce ingots or less including packaging materials) and $10 for each additional pound. International customers please be aware that your country may levy import duties and/or VAT taxes on your purchase from us. For orders of $99 or under, domestic shipping is $9.95. ![]() Domestic shipping is free for all orders over $99 (enter code free shipping at checkout). If you are not completely satisfied with any purchase from us, you have 30 days to return it for a full refund (buyer to pay return shipping). As we suggest with all of our metals please keep them intact in a safe place, do not ingest, and keep out of the reach of children.Įach ingot will be shipped with an assay certificate and every shipment will include our velvet logo bag. Inhalation of its oxidized powder or dust forms can be harmful and has been linked to cancer in rats. Antimony is mined as a principal product or as a byproduct of the smelting of base-metal ores in 15 countries, which includes the United States (Montana, New. Antimony in the solid form we supply is considered safe. As always, weight and purity are guaranteed by Rare World Metals Mint. As with our other ingots, there can be edge dings and other tiny imperfections which do not detract from the inherent value of this rare metal. Unfortunately this reflective tigonal pattern does not photograph well so we think you'll be in for a happy surprise when you receive it as we believe this is one of our most beautiful ingots and our pictures have never done them justice. Its trigonal crystallization pattern is evident in our ingots and is similar to that seen in our tellurium ingots. These ingots are lightly polished, similar to the one pictured. Inscribed on our ingots are the chemical symbol (Sb), purity (99.99%), weight (one troy ounce), and a serial number (this number is unique and will vary). This may indicate future price volatility. It sits high on the "risk list" published by the British Geologic Survey (see below link) as do several of our other metals. It also has growing uses in microelectronics. It is predominantly used in flame retardant compounds, in lead batteries, and in other alloys either with lead or with other metals to produce lead free products such as solders and bullets. It has been estimated that about 80 or 90% of worldwide antimony production comes from China and that established global reserves of this metal may be depleted in as few as 13 years. Relatively rare, it is sometimes found as a base metal, but more often occurs bound to other elements in one of up to 100 mineral compounds. ![]() Antimony salts are used in the rubber and. The ore called stibnite is the predominant ore from which antimony is produced and where it chemical symbol Sb originated. Antimony, the 51st element on the periodic table (symbol: Sb), is a shiny, silver-gray metal that has been used by mankind for millennia. Stibnite is used for metal antifriction alloys, metal type, shot, batteries and in the manufacture of fireworks. The first naturally occurring pure antimony metal was discovered in 1783 by Anto von Swab in the Sala Silver Mine in Sweden. The procedure to obtain its pure metallic form was first described in the posthumously released book "De la Pirotechnia" in 1540 by Italian metallurgist Vannoccio Biringuccio. One of the earliest uses of its sulfide was as an eye cosmetic in Egypt as early as 3100 BC with the advent of the cosmetic palette. Antimony has been used since ancient times. ![]()
