To rapidly and uniformly densify silicon carbide powder with flash hot pressing, the team experimented with a conventional spark plasma sintering device, tweaking the design of the sintering die. “Conducting flash sintering in a device designed for spark plasma sintering requires extra thought in die design,” the authors write in the open-access Scientific Reports paper describing their work.

Next EUV Challenge: Pellicles - Semiconductor Engineering
In the lab, Samsung has explored the development of an EUV pellicle, based on single-crystalline silicon materials with a boron carbide (B4C) capping layer. With a 250-watt source, Samsung’s B4C pellicle heats up to 323 degrees Celsius, compared to 686.1 degrees Celsius for a polysilicon merane.
Emery paper - Wikipedia
Originally, emery paper was made from milled emery rock, bonded or sized to paper often with an animal glue for water resistance. Today, synthetic adhesives are used in place of natural glues and silicon carbide (SiC) is often substituted for emery, silicon carbide being slightly harder , and more durable with less tendency to fracture than corundum.
Abstract Paper no. R3.19Positron lifetime spectroscopy was employed to study the as-electron-irradiated (10 MeV, 1×10 18 cm -2) n-type 6H silicon carbide sample in the measuring temperature range of 15 K to 294 K. Isochronal annealing studies were also
Hard Face – Mc Nally Institute
HARD FACE H002A good mechanical seal should run leak free until the carbon-graphite seal face wears away. This is the same way we decide if we are getting good life with our automobile tires. The tires should not go flat or the sidewalls “blow out”. The tire tread
Open Access Article 3. Energetic Convergence of a New Hybrid Mixed Finite Element , Pages: 291-312 M.R.T. Arruda, P.F.T. Arruda and B.J.F. Lopes PDF (550K) Abstract: This paper presents a new hybrid double mixed stress (4f-HMS) model, for the static analysis of isotropic plane structures, in which it is assumed a physically and geometrically linear behaviour.
Comprehensive Study on Gate Driver for SiC-MOSFETs with Gate …
This paper presents a gate driver topology designed for silicon-carbide (SiC) MOSFETs to achieve higher speed, lower loss, and lower noise than conventional gate drivers. We proposed a gate boost circuit to reduce the switching losses and delay time, without
