sharpening - Can I sharpen a carbide tool with sandpaper

In general: No. (Unless you buy Silicon Carbide sandpaper)Every "ordinary" sandpaper is made using either Silicon Dioxide (SiO 2) or (more expensive) Aluminum Oxide (Al 2 O 3).The Mohs scale is one way of assessing hardness, its principle is "harder materials scratch softer ones, not vice versa".Harder materials have higher nuers on the Mohs scale.

Reduction of Igneous Rock With Carbon and Silicon Carbide

In the reaction of granite (37.5 g) with silic6n carbide (12.5 g), almost no reaction occurred below 11 00 C; about 7 percent of the silicon carbide was reacted between 1100 and 1500 C. As the temperature was increased from 1500 to 1740 C, the reaction rate gradually increased and then rapidly decreased when most of the carbon was consumed.
