12/4/2021· The emissivity of merane structures based on silicon carbide of the 6H polytype has been experimentally investigated at high temperatures. The dependence of the monochromatic emissivity of the SiC meranes on their thickness has been obtained.
The carbon-fiber-reinforced silicon carbide (C/SiC) brake disks weigh around 50 percent less than conventional gray cast-iron brake disks. Other advantages include much better braking response, higher fading stability, very good control, better directional stability and prevention of brake dust.

1/9/2020· In summary, a ZrO 2 /SiC ceramic merane was prepared with pure silicon carbide as the substrate and intermediate layer, and zirconia as the selective layer. Because of the exclusion of low-melting oxides, both the chemical corrosion and thermal resistances of the merane were improved, thus it could be used in strong acidic or alkaline conditions, or high temperature environment.
Cerane A/S produces a unique patented Silicon Carbide (SiC) ceramic flat sheet merane from its facilities in Lynge, Denmark. Cerane has provided meranes to OEM & System Integrators in more than 50 countries in a wide variety of appliions including drinking water and wastewater reuse within both the industrial and municipal market.
Product Advantages. High performance in flux: up to 650 l/m2h. High water recovery rate: 98-99,5 %. Ceramic merane material offers superior mechanical, thermal and chemical durability. Long merane life time: +20 years.
Furthermore, silicon carbide ceramic meranes exhibit a high degree of hydrophilicity (a tendency of a surface to become wet or to absorb water) that results in unique flux (low energy consumption). Silicon carbide is also very durable with a hardness second …

Alternatively, ceramic meranes, particularly, silicon carbide (SiC) meranes showed excellent potential due to their high mechanical strength, good thermal and chemical resistance, superior hydrothermal stability and good selectivity for hydrogen with reasonable flux.
Under a specific sintering temperature, bulk densities and the merane is more selective: linear shrinkages for the specimens are ranked in the following 1/2 order: A8 . A5 . A3.

1/11/2004· A PCS merane prepared with 1% PS had a H 2 permeance of 4 × 10-8 mol m-2 s-1 Pa-1 and an ideal H 2:N 2 selectivity of 20 at 773 K. The meranes were unstable in Ar at 1223 K. When exposed to a 7.8 wt% H 2 O in He mixture at 773 K, the H 2 and N 2 permeances decreased by half during the first 24 h, and slowly after that for the remainder of the 72 h of the experiment.
