AI‐Driven Properties Prediction in Si3N4 Ceramics: Image‐Based and Processing Parameter Strategies
International Journal of Applied Ceramic Technology, Volume 23, Issue 3, June 2026.ABSTRACT This review presents AI‐based approaches for predicting key properties of silicon nitride (Si3N4) ceramics from both microstructural images and process parameters. Convolutional neural networks (CNNs) successfully predicted bending strength, fracture toughness, and dielectric breakdown strength directly from microstructural images, with higher

Oxidation of Borides and Carbides with Y2O3 and Ta Additions
, 2012 The study presented here describes an investigation of an oxidation scale of a fully-sintered Y2O3-ZrB2-TiC composite exposed in air at 1173K. Upon oxidation of the boride/carbide, a ZrO2-TiO2 was expected to form similar to the ZrO2-SiO2 dual scale of ...

International Journal of Applied Ceramic Technology, Volume 23, Issue 3, June 2026.ABSTRACT A multilayer coating system was developed as an ablation and thermal protection measure for C/C composites. The multilayer coating architecture consists of SiC, ZrB2‐SiC (ZBS), and ZrC‐ZrO2 (ZZC) sublayers with a Sm2O3‐ZrO2 (SZC) topcoat.

International Journal of Applied Ceramic Technology, Volume 23, Issue 3, June 2026.Silicon nitride samples were slip cast using ytterbium oxide sintering aids to fabricate porous materials for radar frequency windows. Varying sintering temperature and ytterbium oxide content were used to tailor microstructure and phase composition. Flexural strength was measured at room temperature and 1000°C.

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.Silicon nitride samples were slip cast using yttrium oxide–aluminum oxide and ytterbium oxide sintering aids to fabricate plates with up to 40% porosity and compare them to a fully dense commercial standard. Silicon nitride plates were tested with an oxyacetylene torch to investigate changes in front and back face temperature, spectral emissivity ...
