While the existence of boron containing minerals such as colemanite, kernite, ulexite and tincal are relatively common in the earth's crust, the production of high purity boron is limited by difficulties separating boron from other elements. Boron is a very hard element that is often used as an abrasive (boron nitride and boron carbide), as well as a dopant to affect conductivity in semiconductors or strengthen neodymium-iron-boron (NdFeB) magnets .
SMI Ltd. stocks and supplies both 95% and 99% min. amorphous boron powder. We are also able to supply 92% min. boron powder and boron nitride upon request. Please do not hesitate to contact us for a current boron price.
A metalloid, elemental boron has some properties of both metals and non-metals. Amorphous boron powder is a light weight brown powder that is used as a dopant to strengthen structural materials including metal alloys and refractory materials. Due to its hardness, boron...Read more...
Boron is an enigmatic metal that can exist as a number of different forms (allotropes) each with different physical and chemical properties. SMI Ltd. stocks and supplies both 95% and 99% min. amorphous boron powder. Our higher purity (99% min.) boron powder contains less than...Read more...
Boron’s high strength properties make it useful in a wide variety of applications, from aerospace components to high strength magnets (Neodymium Iron Boron – NdFeB – magnets). Boron is also used in the semiconductor industry as a dopant, as well as in the formation of high hardness compounds...Read more...
Boron nitride (BN) is an extremely hard compound with excellent thermal and chemical stability. These properties make boron nitride ceramics extremely useful in high temperature equipment, including alloys for cutting tools, resins, plastics and rubbers. Boron nitride is also applied in a number of electronics applications, such as semiconductors, as well as...Read more...
