Abstract SiO 2 ‐Al O 3 ‐CaO‐based glass (10–60 wt%)/mullite composites were investigated for the LTCC and radome applications. The optimum densification temperatures decreased from 1550°C (10 wt% glass) to 1400°C (30 by means of liquid‐phase sintering, 850°C–825°C (50–60 viscous phase sintering. XRD analysis showed that mullite was main as well in situ crystallized anorthite after 825°C. composite with 20 a suitable candidate applications (bulk density = 2.86 g/cm sintering at 1450°C,...
Abstract Mullite/glass/nano aluminum nitride (AlN) filler (1–10 wt% AlN) composites were successfully fabricated for the low‐temperature co‐fired ceramics applications that require densification temperatures lower than 950°C, high thermal conductivity to dissipate heat and expansion coefficient matched Si reliability, low dielectric constant signal transmission speed. Densification ≤825°C all due viscous sintering of glass matrix. X‐ray diffraction proved AlN neither chemically reacted with...
Al2O3/glass/hBN composites were successfully fabricated for the LTCC applications. Alignment and homogeneous distribution of platelet hBN particles during tape casting allowed high (5 wt%) loading as well facilitated densification at 800°C (density 2.65 g/cm3, apparent porosity 0.7%). XRD results proved that neither chemically reacted with other phases nor decomposed temperature, which was critical to increase thermal conductivity same time decrease dielectric constant. Dielectric constant...
This work focuses on the fabrication and evaluation of a passive wireless sensor for monitoring temperature corrosion metal material at high temperatures. An inductor-capacitor (LC) resonator was fabricated through screen printing Ag-based inks dense polycrystalline Al
Elektrolitik kaplamalara alternatif oluşturan ve dışarıdan herhangi bir elektrik ihtiyacına gerek duymadan gerçekleşen otokatalitik akımsız kaplamalar birçok endüstriyel alanda kullanılmaktadır. Homojen kaplama kalınlığı elde edilmesi, yüksek sertlik, iyi korozyon aşınma direncine sahip olması, kaplamaları oldukça yaygın hale getirmektedir. Ayrıca karmaşık şekilli parçalara da uygulanabilmesi avantajları arasında yer almaktadır. Bu çalışmada Ni-P kaplamaların metalik nikel fosfor içerikleri,...
Bu çalışmada Al2O3/cam/ZrO2 kompozitlerin yoğunlaşma davranışı, faz oluşumu, sertliği ve dielektrik özellikleri karakterize edilmiştir. Alümina, CaO-Al2O3-SiO2 bazlı ticari cam nano zirkonyum oksit başlangıç malzemesi olarak kullanılmıştır. ZrO2, C55 tozuna (ağırlıkça %45 Al2O3+ ağırlıkça %55 cam) farklı miktarlarda (örneğin, %47 %57 ZrO2 %68 içeren C55) ilave Al2O3/Cam Al2O3/Cam/ZrO2 numuneleri tek eksenli kuru presleme yöntemiyle üretilmiştir. Optimum yoğunlaştırma sıcaklığı için 800 ˚C,...
