Abstract

Telah dilakukan sintesis komposit keramik zirkonium titatzatzirknia (ZrTiO/Zr02) dengan metode pencampuran serbuk-larotan. Pembentulcan ZrTi04 melibatlcan realest antara serbulc zirlconia (Zr)3) dengan Jarotan titanium trilclorida 15% (Ti CL3). Karakterisasi terhadap serbulc pralceramilc hasil proses pencampuran meliputi pengujian sedigraf untuk mengetahui distribusi ukuran partilcel, pengujian analisis termal DTA/TGA, difraksi sinar-x dan SEM dilakukan juga analisis kuantitatiffraksi berat fase yang terbentuk dengan memanfaatlcan parameter keluaran hasil penghalusan metode Rietveld. Proses pencampuran serbu larutan menghasilkan distribusi artilcel antara 0.6-35 pm. Berdasar hasil analisis temtal pembentukan keramik zirkonium titanat terjadi pada 1350°C. Hasil pengujian difraksi sinar-x menunjukkan adanya tigafase pada bahan yaitu fase zi rkonia, titania dan zirkornium titanat. Penghalusan Rietveld menghasilkan fraksi berat zirkonia 73%, zi konium titanat 25.89%, titan fa 1.11% untuk bahan I, sedang pada bahan 11 teridentifikasi adanya fase zirkonia sebesar 56.54%, 40.48% fase zi konium titanat serta tit ani a sebesar 2. 98% Pengamatan SEM menunjukkan porositas yang besar, pengujian porositas menghasilkan apparent porosity sebesar 21.02{1)%. Hasil SEM juga mengilustrasikan adanya microcracking pada bahan uji

The synthesis of zirconium titanate ceramic composite (ZrTiO2/Zr02) has been carried out by powder-solution mixing method. The formation of ZrTiO4 involves the interaction of zirconia (Zr)3 with 15% titanium trichloride (TiCl3). The characterization of the pre-ceramic composite resulting from the mixing process includes sedation testing to determine the particle size distribution, DTA/TGA thermal analysis, X-ray diffraction and SEM, as well as quantitative analysis of the weight fraction of the formed phases by utilizing the output parameters of the Rietveld refinement method. The powder-solution mixing process produces an particle distribution between 0.6-35 pm. Based on the results of the thermal analysis, the formation of zirconium titanate ceramics occurs at 1350°C. The results of X-ray diffraction testing indicate the presence of three phases in the material, namely the zirconium, titania and zirconium titanate phases. Rietveld refinement produced a weight fraction of zirconia of 73%, zikonium titanate of 25.89%, titan a of 1.11% for material I, while in material 11, the presence of zirconia phase of 56.54%, zikonium titanate phase of 40.48% and titan a of 2.98% was identified. SEM observations showed large porosity, porosity testing produced an apparent porosity of 21.02%. SEM results also illustrated the presence of microcracking in the test material
