  • Silicon Nitride (Si3N4) and Sialons - Fraunhofer IKTS

    Silicon nitride (Si 3 N 4) is a non-oxide ceramic material with a unique combination of outstanding properties.These include a high fracture toughness (5-8 MPa·m ½) in combination with a high flexural strength (800-1000 MPa) and a low coefficient of thermal expansion (3.5·10-6 K-1).This leads for example to an excellent thermal shock resistance. Furthermore, advanced ceramics are ...

    2020-12-14 · The release of nitrogen and silicon is the chemical origin of Si 3 N 4 ’s biological effectiveness. A hydrolysis process initiates the protonation of amino groups at the Si 3 N 4 surface. The electrophilicity at the adjacent silicon sites increases, which in turn leads to the propensity of these sites to undergo nucleophilic attack by water.

  • Activity and Mechanism of Action of the Bioceramic

    Biological Filter Media All fish tanks need biological and mechanical filtration to maintain a healthy environment. Swell Ceramic Bio Media has a very porous surface which allows a much higher flow rate through the filter unlike some media which will slow it down as it becomes clogged very easily.

    An electrostatically deformable, gold-coated, silicon nitride membrane mirror was used as a phase modulator to compress pulses from 92 to 15 fs. Both an iterative genetic algorithm and single-step dispersion compensation based on frequency-resolved optical gating calibration of the mirror were used to compress pulses to within 10% of the transform limit.
