Sintesa dan struktur kristal keramik garnet Y3 Fe5-5X AI5x O12

" The effect of Fe substitution on AI of garnet ceramic with chemical formula Y3Fe5_5XAl5 O12, where x (synthesis) of 0, 0.05, 0.15, and 0.25, has been investigated. Sample in this study were synthesized using wet oxydation method, Hot Kerosene Drying (HKD). All constituents were used in liquid form from YCI3.6H2O, AIC13, and Fe2O3 and HCI, which were reagents with purity better than 99%. Thermal 'analysis (DTA) was used to investigate calcination and sintering temperature. The ... "

Pengukuran warna glasir keramik

" This is research about color measurements of ceramic glaze with measure the reflectance of glaze ceramic sample that used spectrophotometer UV-VIS and color different calculation, to get quantitative color standard in the ceramic product and to look for the color matching method in each batch of ceramic glaze product that compared with product standard. Ceramic sample used four base colors, these are Blue 4571, Green AV-I500, Yellow DKC-9, and Red 270066, that make variable between ... "

Pengaruh komposisi Al2O3 dan suhu sintering terhadap karakteristik keramik porselin

" Telah dilakukan pembuatan keramik porselin dengan menggunakan bahan baku lokal dengan komposisi: 35% feldspar, 35% kaolin dan 30% silika (berat) serta ditambahkan 0 - 40% Al203 (dari berat total). Proses pembentukan dilakukan dengan menggiling bahan baku menggunakan ball mill hingga lolos ayakan 200 mesh, dicetak tekan sebesar 200 kg/cm2 dan selanjutnya disinter pada suhu: 1300, 1350, 1400, 1450, dan 1500°C. Identifikasi fasa yang terbentuk diamati dengan menggunakan XRD. Sifat fisis dan mekanik yang diamati antara ... "

Pembuatan Keramik Untuk Material Sensor omposit CaF2/SiC

" Pengembangan material-material baru diharapkan dapat memenuhi tuntutan dari perkembangan teknologi yang ada. Material tipe komposit yang merupakan campuran dari dua atau lebih elemen bahan secara makro menjadi salah satu alternatif yang sedang dikembangkan saat ini. Salah satunya adalah penggunaan komposit sebagai sensor mekanik. Komposit yang ditinjau memiliki elemen CaF2 sebagai matriks dan elemen SiC sebagai penguat. Tujuan dari penelitian ini adalah mempelajari pengaruh dari penambahan SiC sebanyak 0%, 10%, 15%, 20%, dan 25% ke dalam ... "

The use of the rietveld method to study the phase composition of cordierite (Mg 2 Al 4 Si 5 O 18 ) ceramics prepared from rice husk silica

" This research presents the use of the Rietveld method to study the phase composition of cordierite (MG2AL4SI5O18) ceramics prepared from rice husk silica, after the samples were sintered at 1300, 1400 and 1500 °C. The formation of cordierite is temperature-dependent as indicated by the relative phase composition obtained from x-ray diffraction patterns for the cordierite and spinel increased markedly with increasing temperature, i.e, from 38.98 to 54.15 wt% and from 11.81 to 17.99 wt % following ...

Willemite-based glass ceramic doped by different percentage of erbium oxide and Ssntered in temperature of 500-1100C: physical and optical properties

" This book investigates the effect of sintering temperature on willemite based glass-ceramic doped with different content of Er2O3. It is the first to report research on producing willemite by using waste materials and using trivalent erbium (Er3+) as a dopant. This book provides a survey of the literature on glass and glass-ceramic, while comprehensive experiments and analysis have been performed on the material used. ... "
