Features PREMIUM QUALITY: The bismuth piece has many interesting properties. It has a relatively low melting point of about 520 degrees Fahrenheit, which makes it useful for alloying with other metals. Bismuth is used to grow beautiful iridescent funnel crystals used in jewellery and art DURABLE TO USE: This thermal conductivity of bismuth is very low, expands, cools, with an extremely high diamagnetic value. Bismuth is a non-toxic and environmentally friendly lead substitute. Bismuth can melt at lower temperatures, has a lower density and is also harder and brittle Suitable for: mainly used in the production of bismuth alloys, medicines, chemical reagents, basic melting point alloys, nuclear reactor refrigerants and so on. This product is a bismuth ingot, the bismuth content is ≥99.99(%), the density is 9.8/cm³ and the weight is 1000g. WIDE APPLICATION --- Our pure crystal widely used in the field of semiconductors, superconductors, flame retardants, pigments, cosmetics, electronic ceramic lamps. SERVICE GUARANTEE --- If you have any questions about our product, please feel free to contact us, we will try our best to solve your problem.
