This paper presents microball end milling of tungsten carbide using a CBN cutter to investigate its capability for machining slots for micromoulds. Crackfree slots were machined at different axial depths of cut by inclining the work piece surface at different angles to the spindle axes to study the influence of these machining parameters on the cutting mechanism and surface finish.

Silicon carbide is an important material in TRISOcoated fuel particles, the type of nuclear fuel found in high temperature gas cooled reactors such as the Pebble Bed Reactor. A layer of silicon carbide gives coated fuel particles structural support and is the main diffusion barrier to the release of fission products.
This paper presents the effect of different preparation methods (milling by ball mill or collision milling by disintegrator) of silicon carbide aggregate (SiCA) on the properties of refractory concrete with cenospheres (CNPs). The different milling methods are known to have a significant effect on the morphology of aggregates, their shape, and ...
(a) Sample preparation A highenergy ball mill with 70 mm in diameter and steel balls with different diameters were employed. The Al powder and SiC particles with different average sizes (25 μm, 5 μm, and 70 nm) at constant weight ratio of ball/powders (, 10) were added to the ball mill .
Direct synthesis of silicon carbide (SiC) nanopowders (size 50–200 nm, BET ~20 m 2 /g) in Si–C system is conducted in an inert atmosphere (argon) using a self‐propagating high‐temperature synthesis (SHS) approach. A preliminary short‐term (, minutes) high‐energy ball milling (HEBM) of the initial mixture, which involves pure Si and C powders, is used to enhance system reactivity.
The invention relates to a preparation method for a silicon carbide ceramic tube or rod.
