the synthesis of nb doped batio3 has been investigated under microwave-hydrothermal (mh) conditions in the temperature of 150°c for only 2 h using c16h36o4ti, bah2o2.8h2o and nbcl5 as ba, ti and  nb sources, respectively.  typical experiments performed on mh processing have not yet reported for nb doped batio3.  in the mh process, the formation of high purity nano tetragonal nb-batio3 was stron...

OBJECTIVE This study evaluated the surface degradation effect of acidulated phosphate fluoride (APF) gel exposure on the glassy matrix ceramics as a function of time. MATERIAL AND METHODS Disc-shaped ceramic specimens (N = 120, 10/per ceramic material) were prepared in stainless steel molds (inner diameter: 5 mm, height: 2 mm) using 6 dental ceramics: 3 indicated for ceramic-fused-to-metal (V...

The development of novels materials represents a new and fast evolving application of research in physics and medicine. Processing synthesis is critical because it generally controls the final properties of the materials, ceramic forming techniques are generally based on powder processing with powder synthesis, forming and sintering. Moreover, ceramic processing has also to consider other techn...

Data are summarized on the synthesis of hydroxyapatite (HA) by wet-chemical processes, solidstate reactions, and hydrothermal treatment. The conditions for HA preparation via precipitation from solutions of calcium chloride, dibasic ammonium phosphate, and aqueous ammonia are discussed at length. Detailed analysis of the fabrication and properties of calcium-phosphate-based ceramics is presente...

Integrated temperature-humidity-sensitive thick-film structures based on spinel-type semiconducting ceramics of different chemical compositions and magnesium aluminate ceramics were prepared and studied. It is shown that temperature-sensitive thick-film structures possess good electrophysical characteristics in the region from 298 to 358 K. The change of electrical resistance in integrated thic...

Sixth millennium BC Dalma ceramics from the northwestern and central Zagros have previously been described as beingimpossible to distinguish using decorative style analysis in spite of the great distance between the two regions. In thisstudy, petrographic (thin section) analysis and a small-scale electron microprobe project was carried out on the ceramicsof the two regions, as well as a small s...

In this chapter, various synthesis routes for PZT powders and fabrication processing techniques for PZT ceramics and films are reviewed. Emphasis is placed on chemical routes, especially the hydrothermal synthesis of PZT powders. The principles of the colloidal chemistry in ceramic suspension and its application to the colloidal processing of ceramics and films, especially when using sub-micron...

Over the past forty years, the technological evolution of ceramics for dental applications has been remarkable, as new materials and processing techniques are steadily being introduced. The improvement in both strength and toughness has made it possible to expand the range of indications to long-span fixed partial prostheses, implant abutments and implants. The present review provides a state o...

In their 2001 book Art & Fear: Observations On the Perils (and Rewards) of Artmaking, David Bayles and Ted Orland share a story about a ceramics teacher who divided his class into two groups. He told one half they would be graded on quantity, so they should “produce as many ceramics you can in one quarter, that will be your grade,” while he told the other half they would be graded based on one ...
