Effects of SiC and MgO on aluminabased ceramic foams filters [PDF]

China Foundry, 2007
Alumina-based foam ceramic filters were fabricated by using alumina, SiC, magnesia powder as major materials. It has been found that this ceramic filter has a uniform macrostructure for filtering molten metals. The influences of SiC and magnesia content,

A Novel Capacitive Cross-Coupling Structure for Ceramic-Filled Cavity Filters

IEEE Access, 2021
Since the probe coupling for cavity filters is unsuitable for ceramic-filled cavity filters, a novel capacitive cross-coupling structure is proposed to improve stopband suppression by introducing transmission zeros. This structure is implemented by first

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Properties of Ceramic Filters [PDF]

, 1996
The mechanical integrity of ceramic filter elements is a key issue for hot gas cleanup systems. To meet the demands of advanced power systems, the filter components sustain thermal stresses of normal operations (pulse cleaning), of start-up and shut-down, and of process upsets such as excessive ash accumulation without catastrophic failure.
