  • Pottery and ceramics have been an important part of human culture for thousands of years. From prehistoric storage jars to tiles on the space shuttles, pottery and ceramics have played a key role in innumerable human endeavors. The art of ceramics is one of the oldest known, dating to prehistoric times. Once heated (fired) to between 350⁰ and 800⁰C, the clay is converted to ceramic and will never dissolve again.

  • VNU Journal of Science, Natural Sciences and Technology 24 (2008) 280-286 In this study, primarily treating waste sludge rich of Cr, Ni, Fe,…generated from electroplating wastewater treatment plant and experimentally methods of utilizing wastes as inorganic pigment in production of bricks were carried out. Economic, technical and environmental efficiency and feasibility, bases to apply to practical conditions were evaluated. The results show that water accounts for about 70% of sludge. Contents of Ni, Cr and Fe are relatively high (20, 4.5 and 2.5%, respectively). ...

  • This paper is the third of a series of preliminary studies of aboriginal ceramic art which are intended to be absorbed into a final work of a comprehensive character. The groups of relics selected for these studies are in all cases of limited extent, and are such as can lay claim to a considerable degree of completeness. It is true that no series of archæologic objects can ever be considered complete, but in exceptional cases the sources of supply may be so thoroughly explored that the development of new features of importance cannot reasonably be expected.

  • Sintering refers to the science and technology of production objects from fines or powders. Being a very complex phenomenon, sintering covers a broad subject field and combines chemistry, physics and mechanics. Sintering deals with various material systems such as metals, non-metals, ceramics, polymers, and their combinations. Processes of sintering may occur in a wide temperature range - in a solid state as well as with participation of a liquid phase.

  • The term ‘architectural tile scheme’ covers a very broad church of ceramic decoration found usually on the inside but also frequently on the outside of buildings. Tiles are superficial to the structure of the building, being used to cover walls, floors and sometimes ceilings for both functional and decorative reasons.

  • For the investigation of art in its early stages and in its widest sense—there is probably no fairer field than that afforded by aboriginal America, ancient and modern. At the period of discovery, art at a number of places on the American continent seems to have been developing surely and steadily, through the force of the innate genius of the race, and the more advanced nations were already approaching the threshold of civilization; at the same time their methods were characterized by great simplicity, and their art products are, as a consequence, exceptionally homogeneous. ...

  • The majority of lead contaminated sites in the Blacksmith Institute’s database are found in Africa, South America, South and Southeast Asia, but the problem of lead pollution plagues most developing countries worldwide. Its uses are varied; in Latin America it has often been utilized for ceramic glazing and in other countries leaded gasoline is still used. In the U.S. lead paint is the cause of a majority of lead exposures and such exposures can be expected in most countries since paint pigments using lead were commonly used worldwide up until a few decades ago.

  • Other materials which may be extracted from MBT processes include glass, textiles, paper / card, and plastics. The most common of these is glass, which may be segregated with other inert materials such as stones and ceramics. These materials are typically segregated and arise as the “dense” fraction from air classifiers or ballistic separation (see Table 2 on mechanical waste preparation technologies). This dense fraction could find application for use as a low grade aggregate; however this would be subject to achieving a suitable quality material.

  • Freeform fabrication technology does not require pre-formed mandrels or tooling; instead, it builds physical objects directly from computer graphical data. This type of technology is also known as layer manufacturing, since it constructs the three- dimensional object layer by layer (Jacobs, 1992; Beaman et al., 1997). The technology has proved that it can help to rapidly provide feedback on design concepts, discover inconsistencies in the design, modify the design, and eliminate inconsistency before fabricating the design.

  • Many types of tool materials, ranging from high carbon steel to ceramics and diamonds, are used as cutting tools in today’s metalworking industry. It is important to be aware that differences do exist among tool materials, what these differences are, and the correct application for each type of material. The various tool manufacturers assign many names and numbers to their products. While many of these names and numbers may appear to be similar, the applications of these tool materials may be entirely different.

  • Casting process is the most direct method of producing a product from the chosen material. Though products in all the three major classes of materials, metals, ceramics and polymers can be produced by this method, casting of metals is by far the most widely used process. The basic steps in the casting process are preparation of the material in the liquid state, transferring the liquid material into a shaping mold, allowing the transformation of liquid material in the mold into a solid form.

  • POWDER METALLURGY has been called a lost art. Unlike clay and other ceramic materials, the art of molding and firing practical or decorative metallic objects was only occasionally applied during the early stages of recorded history. Sintering of metals was entirely forgotten during the succeeding centuries, only to be revived in Europe at the end of the 18th century, when various methods of platinum powder production were recorded (

  • From high-performance, economical and environmental points of view, Powder metallurgy process shows remarkable advantages in production of parts and components due to their special compositions by elemental mixing and 3-dimensional near net shape forming methods. Powder metallurgy process can be applied to not only metal materials but also ceramics and organic materials, which both are employed as structural and electrical products.

  • Continuing work by Atraverda on the production of a composite-laminate form of the Ebonex® material, that can be cheaply formulated and manufactured to form substrate plates for bipolar lead–acid batteries, is described. Ebonex® is the registered trade name of a range of titanium suboxide ceramic materials, typically Ti4 O7 and Ti5 O9 , which combine electrical conductivity with high corrosion and oxidation resistance. Details of the structure of the composite, battery construction techniques and methods for filling and forming of batteries are discussed.
