Comparison of Materials Choices for Heat Exchanger Tubes

Oct 26, 2018· For heat-exchanger tubes, typically silicon-carbide (SiC)-based ceramics are selected. A particular SiC called Hexoloy is an alpha phase sintered silicon carbide developed and produced by Saint-Gobain. The direct sintering process provides Hexoloy with some of its most significant benefits, many of which are above those achieved by SiC that are

Shrinking core like fluid solid reactions—A dispersion

Feb 13, 2012· Commercial silicon carbide powder (Carborundum, Alfa Aesar) was chlorinated at 1000 °C in a horizontal tubular reactor (alumina-tube, d=3.2 cm, l=1.3 m, coated with a graphite foil at the inner wall). The powders were placed in a graphite crucible of 8 cm length. The crucible is open in the front.

Extrusion dies | Plansee

Molybdenum-hafnium carbide (MHC) is highly temperature-resistant, has a high level of thermal conductivity, a low coefficient of thermal expansion and a high recrystallization temperature. MHC retains its shape even when used at temperatures of up to 1 550 °C. At temperatures up to 800 °C, MHC is suitable for use in die inserts.

Silicon carbide manufacturing process - GAB Neumann

Silicon carbide (SiC) is a compound of silicon and carbon with a chemical formula of SiC. The simplest manufacturing process for producing silicon carbide is to coine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1600°C (2910°F) and 2500°C (4530°F).

Transphorm’s GaN Used in HZZH’s 98 Percent Efficient Power

The GaN devices lower the power module’s switching and driving losses, leading to the ZHR483KS outperforming preceding modules that used superjunction Silicon MOSFETs. “We sought a power transistor that would enable us to develop a more efficient yet cost-effective solution for our customers,” said Dr. Guo, CTO, HZZH.
