Objective: Zirconium oxide has gained the spotlight during the recent years as a high strength ceramic material. However, despite its mechanical superiorities, it forms a weak bond with different synthetic substrates and tissues due to its neutral nature and resistance against chemical agents. Therefore, it is important to improve the bonding technique in order to prevent microleakage and incre...
The Optical Effect of Zirconia Background , Ceramic Thickness , and Cement on All - Ceramic Material
Highly transparent and homogeneous hybrids containing a single nano-sized inorganic oxide domain were synthesized from poly(methyl methacrylate) (PMMA) and aqueous dispersed zirconium oxide nanocrystals (ZrO2-NCs) in the presence of a coupling agent, 3-(methacryloxy)propyl-trimethoxysilane (MPTS), which was grafted onto the surface of ZrO2-NCs by zirconium hydroxide (Zr-OH) surface groups. The ...
Titanium oxide (rutile, TiO2) and zircon (ZrSiO4), known insoluble ceramic materials, are commonly used for coatings of implant materials. We investigate the release of zirconium, titanium, aluminum, iron, and silicon from different micron-sized powders of 6 powders of natural rutile (TiO2) and zircon (ZrSiO4) from a surface perspective. The investigation includes five different synthetic body ...
Hafnium and zirconium oxide films were prepared by atomic layer deposition (ALD) from dialkylamido precursors. Water was used as the oxygen source. Nanolaminates of hafnium, zirconium and aluminum oxide were also prepared. Atomic force microscopy was used to characterize the surface morphology of 10–100 nm thick films grown from 501C to 3001C. X-ray diffraction was used to characterize the film...
One of the ways to waste energy in buildings is wasting it from the walls. For this reason, insulating materials are used to prevent the loss of energy in buildings. Typically, common insulations are high thickness and thin coatings are used less. The purpose of this research is to introduce nanocomposite thin polymer coatings and its effect on thermal conductivity. For achieving this, chemical...
