Silicon carbide coating of nitinol stents to increase …

1/10/2008· For this in vitro study, an amorphous, semiconducting, hydrogen-rich, phosphorous-doped silicon carbide coating (PROBIO, BIOTRONIK, Germany) was applied on self-expanding nitinol stents. The way of action of this particular coating is to decrease activation processes in the coagulation cascade, e.g., reduction of fibrinogen to fibrin, which is caused by electron transfer from the protein to

properties of sand grinding

Silicon Dioxide, High Purity (SiO2) Silica Sand Silica sand products are marketed in a wide range of grades, including extremely fine grades known as flours. The chemical compound silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon with a chemical formula of SiO2 and has been known for its hardness since antiquity.

Synthesis and Characterization of Crystalline Silicon …

In this paper, a simple method to synthesize silicon carbide (SiC) nanoribbons is presented. Silicon powder and carbon black powder placed in a horizontal tube furnace were exposed to temperatures ranging from 1,250 to 1,500°C for 5–12 h in an argon atmosphere at atmospheric pressure. The resulting SiC nanoribbons were tens to hundreds of microns in length, a few microns in width and tens
