Silicon carbide - Import export

Like oxides and nitrides, Silicon Carbide (SiC) is a very hard-wearing material, again requiring diamond-grinding methods to process once fired. Although not exclusively, carbides are used mainly for applications in which physical wear is a major consideration. They are amongst the hardest materials available.

The BSC grinding materials are widely used in the abrasive tools manufacturing and fixed-abrasives - rougher, cutting-off and grinding; tools on a flexible base - coated abrasives, in the process of loose abrasive grains grinding. The BSC grinding materials are used: in the process of iron and nonferrous metals, carbon, glass and ceramics, stone, concrete, bricks and chamotte, wood substance, plastics, leather, rubber, and other hard, tough, brittle, alloys, and materials of natural and artificial origin treatment; in the refractory and ceramic industries as a component for moldings and antipenetration washes, in the process of crucibles for casting of non-ferrous and precious metals production, for wash troughs. Refractory products of silicon carbide abrasive materials have high thermal conductivity, heat resistance (deformation starting above 1500 C), resistance to acid slags.

The microDICE™ laser micromachining system leverages TLSDicing™ (thermal laser separation) – a unique technology that uses thermally induced mechanical forces to separate brittle semiconductor materials, such as silicon (Si), silicon carbide (SiC), germanium (Ge) and gallium arsenide (GaAs), into dies with outstanding edge quality while increasing manufacturing yield and throughput. Compared to traditional separation technologies, such as saw dicing and laser ablation, TLS Dicing™ enables a clean process, microcrack free edges, and higher resulting bending strength. Capable of dicing speeds up to 300mm per second, the microDICE™ system provides up to a 10X increase in process throughput compared to traditional dicing systems. Its high throughput, outstanding edge quality and 300mm wafer capable platform enables a true high volume production process, especially for SiC based devices.

Over the years it has been successfully used in a wide and interesting field of applications ranging from automotive engine components to roller bearings for the most exclusive skateboards (right).

WIWOX® MT micro blasters are used for precise blasting with blasting nozzles from 0.4 – 1.8 mm. Surfaces can be smoothed, matted, deburred or cleaned. All mineral media, e.g. glass beads, broken glass, corundum, silicon carbide in the grain size range from 0 to 300 mμ serve as blasting media. The abrasive is used only once. The blasted surface is reproducible. Only a compressed air connection is required to operate the equipment. Micro-Tip fine blast units are suitable as portable free blast units or in combination with a blast cabinet. Micro-Tip fine blasting technology is available as a pressure or injector process. All units are equipped with foot pedal, pressure regulator, manometer and carbide nozzles.

Grinding is unsteady due to changes in the bond, abrasive grain, and wheel topography, affecting forces, surface, and geometric accuracy. To maintain optimal results, a periodic conditioning cycle restores the wheel's grinding ability, optimizing performance, cost efficiency, and surface finish.
