Silicon Wafer Processing | How Are Silicon Wafers Made?

Because of the silicon’s hardness, a diamond edge saw carefully slices the silicon wafers so they are slightly thicker than the target specifiion. Cleaning The final and most crucial step in the manufacturing process is polishing the wafer.

Refractory | industrial material | Britannica

Refractory, any material that has an unusually high melting point and that maintains its structural properties at very high temperatures.Composed principally of ceramics, refractories are employed in great quantities in the metallurgical, glassmaking, and ceramics industries, where they are formed into a variety of shapes to line the interiors of furnaces, kilns, and other devices that process

Plasma Etching techniques including RIE, PE, ICP, and …

With a Planar ICP, etch profiles are typically anisotropic, and the very high Ion density makes this type of ICP source ideal for etching hard materials such as Quartz, and Silicon Carbide. The Planar ICP flat coil can cause issues with uniformity across the substrate, and various techniques have been used to reduce this effect such as moving the chuck height, and adding magnetics to shape the

How to form silicon carbide ceramic foam filter

The present invention relates to a technique for forming silicon carbide coated ceramic foam filters for use in filtering molten metal, especially copper, iron and related alloy melts.

Materials | Free Full-Text | Study on Rheological Behavior …

A colloidal stability study of a nonaqueous silicon carbide suspension is of great significance for preparing special silicon carbide ceramics by colloidal processing. In this paper, three different chemical dispersants, which are amphiphilic, acidophilic, and alkaliphilic, are selected to compare their ability to stabilize nonaqueous slurries of silicon carbide. The analysis of the flow index

Grades - General Carbide

Tungsten carbide (WC), also referred to as cemented carbide, is a composite material manufactured by a process called powder metallurgy. Tungsten carbide powder, generally ranging in proportion between 70%-97% of the total weight, is mixed with a binder metal, usually cobalt or nickel, compacted in a die and then sintered in a furnace.

What are carbide tips? | HowStuffWorks

Carbide tips do get dull eventually. You sharpen them using the same techniques you would use with tool steel, but because they are so hard, you use a different abrasive. Something coated in diamond or a carbide abrasive wheel is common. If you''ve read How Diamonds Work, you know that diamond (pure crystalline carbon) is the hardest material there is.
