Sep 28, 2005 A boron nitride (BN) nanostructure, conical BN nanorod, has been synthesized in a large quantity on Si substrates for the first time via the ball‐milling and annealing method. Nitridation of milled boron carbide (B 4 C) powders was performed in nitrogen gas at 1300°C on the surface of the substrates to form the BN nanorods.

Nanotube growth during annealing of mechanically milled Boron

Jan 01, 2003 Boron powder, finely ground in a tungsten carbide ball mill in an ammonia atmosphere, has been annealed at 1200 °C in flowing nitrogen to produce small quantities of cylindrical BN nanotubes, both as isolated individuals and grouped into ropes. Thick-walled conical BN tubes are abundant in specimens annealed for longer times, and their growth was catalysed once WC debris was converted

Tapered End Mills McMaster-Carr

End mills have a square cut style for milling square slots, pockets, and edges. All are noncenter-cutting for operations where the sides of the teeth do most of the work, such as shoulder milling, contouring, and finishing. They cannot be used for plunge cuts. R8-shank end mills have internal threads on the tapered end for connecting to a drawbar.
