Boart Longyear John Hoffmeister as president and chairman of the board of the company. FACTS was dissolved when Boart International (a wholly owned subsidiary of Anglo American) bought out CDP's interest in Longyear. In 1974, Boart International invested capital which helped Longyear to become the world's leading manufacturer of diamond bits. Boart Longyear engineers in North Bay, Ontario, secured a reliable source of high-performance synthetic diamonds, which triggered the development of a new bit design – the impregnated-diamond bit. With decades of powder metallurgy experience behind them, Longyear engineers set out to develop a new crown that consisted of synthetic diamonds evenly
High-level radioactive waste management In order to store the high level radioactive waste in long-term geological depositories, specific waste forms need to be used which will allow the radioactivity to decay away while the materials retain their integrity for thousands of years. The materials being used can be broken down into a few classes: glass waste forms, ceramic waste forms, and nanostructured materials. The glass forms include borosilicate glasses and phosphate glasses. Borosilicate nuclear waste glasses are used on an industrial scale to immobilize high level radioactive waste in many countries which are producers of nuclear energy or have nuclear weaponry. The glass waste
