الفيزياءTags : Porcelain Zinc oxide Titanium oxide Mechanical properties dielectrical properties Porcelaine oxyde de zinc oxyde de titane propriétés mécaniques propriétés diéléctriques البورسلان أكسيد الزنك أكسيد التيتان خصائص ميكانيكية خصائص عزلية Index. décimale : 530 الفيزياء Résumé : The aim of this work is to prepared porcelain with high mechanical and dielectric properties by
using economical native raw materials without providing ideal high-cost conditions. The basic
porcelain composition was selected consisting of 30 wt% kaolin, 45 wt% potash-feldspar and 25
wt% quartz. It was prepared by sintering the mixture at different temperatures (1140–1260 °C).
The optimum sintering conditions gave a bulk higher density (2.41 g/cm3) and excellent
mechanical properties. The three point flexural strength, Vickers micro-hardness of porcelains
were 205 MPa and 6.8 GPa, respectively. Dielectric measurements have been carried out at 1
KHz from room temperature to 200 °C. The dielectric constant, dielectric loss tangent, and
resistivity of the porcelain sample sintered at 1160 °C were 25, 0.008 and 9 x 1013 .cm,
respectively. So these values reveal that the porcelain is a good insulator. The mechanical and
dielectric properties of porcelain are improved by addition of titanium oxide and zinc oxide. The
addition of titanium oxide improved both mechanical and dielectrical properties. The optimum
sintering conditions gave a higher bulk density (2.47 g.cm−3) and excellent mechanical
properties. The three point flexural strength (3PFS), Vickers micro hardness of samples
containing 5 wt TiO2 and sintered at 1160 °C were 238 MPa, 12.3 GPa , respectively. The
dielectric constant, dielectric loss tangent of samples containing 5 wt TiO2 sintered at 1160 °C
for 2 h were: 31,0.005, respectively. These values were permitted to confirm that this is typical
insulating material. The mechanical properties of this latter may candidate it to be used in many
fields and several applications. Moreover, the addition of zinc oxide improved both mechanical
and dielectric properties. The optimum sintering conditions gave excellent mechanical
properties: The three point flexural strength, Vickers micro hardness of samples containing
5wt ZnO and sintered at 1160 °C were 242 MPa, 14.5 GPa, respectively. But it did not have a
significant impact on the dielectric properties. Besides, the maximum value of the three point
flexural strength achieved for the samples containing 5 wt TiO2 and 5 wt ZnO are nearby
that of the flexural strength of porcelain containing 5 wt% TiO2 and 30 wt % alumina (about 240
MPa). In other words, the presence of 30 wt % alumina in their product well confirm the benefic
effect of the used raw materials (saving 30 wt % alumina) on porcelain strengthening.Diplôme : Doctorat en sciences En ligne : ../theses/physique/AKAS4189.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=10685 دراسة الخصائص الفـيزيـائـية للبورسلان المحضر إنطلاقا من مواد أولية محلية [texte imprimé] / سعاد قصراني, Auteur ; عبد الحميد حرابي, Directeur de thèse . - جامعة الإخوة منتوري قسنطينة, 2017 . - 141 ورقة. ; 30 سم.

PhysiqueTags : البورسلان الميليت الكورندوم الكورديريت porcelaine mullite corindon cordiérite porcelain corundum cordierite Index. décimale : 530 Physique Résumé : In this work we are concerned with the preparation and characterization of porcelain. Different formulations of porcelain in various proportions have been studied to evaluate their ability to be used for industrial purposes.
The main conclusion to be drawn from this work is the possibility of the preparation of porcelain, from local raw materials. At the beginning, we have followed one method of crystallisation; a solid state reaction. Relying on this.0 method, we studied the influence of addition of small amounts of TiO2 and Al2O3 on sintering and crystallisation of the compounds. We have used aluminium hydroxide and talc in order to crystallize other compounds like mullite and corundum and cordierite.
In addition, we have studied some properties of the compounds based on X-ray diffraction, DTA, MEB, FTIR, etc. These compounds can be used in electrical insulation.Diplôme : Doctorat en sciences En ligne : ../theses/physique/KIT6419.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=9446 Impact des additions en petites et grandes proportions sur les propriétés physiques de la porcelaine.
