High Thermal Conductivity of Silicon Nitride Ceramics: A Review

open access: yesKONA Powder and Particle Journal
Silicon-nitride ceramic substrates exhibit high thermal conductivity, high electrical insulation, high mechanical strength, low expansion. The Cu-clad ceramic substrate is the key material for the encapsulation of insulated gate bipolar transistor ...

Research on Crack Propagation Mechanism of Silicon Nitride Ceramic Ball Bearing Channel Surface Based on Rolling Friction Experiment

open access: yesApplied Sciences
The application feedback on existing silicon nitride ceramic bearings and RCF experimental research all indicate that the primary failure mode of silicon nitride ceramic bearings is material spalling on the contact surface. Spalling failure occurs due to

Silicon Nitride Bearings for Total Joint Arthroplasty

open access: yesLubricants, 2016
The articulation performance of silicon nitride against conventional and highly cross-linked polyethylene, as well as for self-mated silicon nitride bearings, was examined in a series of standard hip simulation studies. Wear rates for polyethylene liners

Evaluation of silicon nitride as a substrate for culture of PC12 cells: an interfacial model for functional studies in neurons.

open access: yesPLoS ONE, 2014
Silicon nitride is a biocompatible material that is currently used as an interfacial surface between cells and large-scale integration devices incorporating ion-sensitive field-effect transistor technology.

A feature extraction method for silicon nitride bearing microcracks based on adaptive gamma and multi-width dynamic thresholds [PDF]

open access: yesAIP Advances
This study aims to address the problems of localized indistinctness, low contrast, and unclear feature recognition in images of silicon nitride bearing surfaces by proposing adaptive gamma variation and multi-breadth dynamic threshold segmentation ...

Selective etching of silicon nitride over silicon oxide using ClF3/H2 remote plasma

open access: yesScientific Reports, 2022
Precise and selective removal of silicon nitride (SiNx) over silicon oxide (SiOy) in a oxide/nitride stack is crucial for a current three dimensional NOT-AND type flash memory fabrication process.

Modelling of High-Power Grinding for Sintering Activation of Silicon Nitride Powders

open access: yesНаука и техника, 2004
The influence of milling conditions (acceleration of milling bodies, ball milling time and medium) on specific surface of silicon nitride powders and iron content in them has been studied in the paper. The sintering kinetics of the samples being prepared

Compact silicon nitride interferometers

open access: yesOptics Express, 2023
We demonstrate a compact silicon nitride interferometer which uses waveguides with the same length and different effective indices instead of similar effective indices and different lengths. In such structures there is no need to have waveguide bends.

Corrosion characteristics of silicon carbide and silicon nitride

open access: yesJournal of Research of the National Institute of Standards and Technology, 1993
The present work is a review of the substantial effort that has been made to measure and understand the effects of corrosion with respect to the properties, performance, and durability of various forms of silicon carbide and silicon nitride. The review encompasses corrosion in diverse environments, usually at temperatures of 1000 °C or higher.
