NEW YORK, Oct. 1 /PRNewswire/ -- Reportlinker.com announces that a new market research report is available in its catalogue. US Specialty Silicas Market http://www.reportlinker.com/p0116413/US-Specialty-Silicas-Market.html US demand to grow 3.7% annually through 2013 US specialty silica demand is projected to increase 3.7 percent per year to $1.7 billion in 2013, led by healthy advances in the large precipitated silica segment. Overall volume gains are forecast to accelerate from the pace...
In the 2,000 or so years since the Roman Empire employed a naturally occurring form of cement to build a vast system of concrete aqueducts and other large edifices, researchers have analyzed the molecular structure of natural materials and created entirely new building materials such as steel, which has a well-documented crystalline structure at the atomic scale.Oddly enough, the three-dimensional crystalline structure of cement hydrate - the paste that forms and quickly hardens when cement...
U.S. Silica expands production of fracturing (frac) sand for the oil and gas markets BERKELEY SPRINGS, W.Va., June 24 /PRNewswire/ -- U.S. Silica Company has begun the construction of a new process facility to expand its production of OTTAWA WHITE(TM) fracturing (frac) sands for the oil and gas markets. The new facility at U.S. Silica's Ottawa, IL plant, which will be completed in the 3rd quarter of 2009, will increase the plant's capacity to produce ISO/API specification frac sand by more...
ZHANGJIAGANG, China, Nov. 14 /PRNewswire-FirstCall/ -- Today, WACKER Chemie AG and Dow Corning Corporation officially started production in the first stage of their new pyrogenic silica and siloxane plants in Zhangjiagang (China). The new plants are key facilities of an integrated silicone manufacturing site developed by both companies to produce materials used extensively in industries including construction, beauty and personal care, power and automotives. Total investment from both...
Shock waves around dusty, young stars might be creating the raw materials for planets, according to new observations from NASA's Spitzer Space Telescope.The evidence comes in the form of tiny crystals. Spitzer detected crystals similar in make-up to quartz around young stars just beginning to form planets. The crystals, called cristobalite and tridymite, are known to reside in comets, in volcanic lava flows on Earth, and in some meteorites that land on Earth.Astronomers already knew that...
By Luntz, Stephen A nanomaterial coating on silica particles could offer the solution to one of the world's oldest and most destructive health challenges: how to remove bacteria and other pollutants from drinking water. In disasters like the Burmese cyclone, many of the deaths come from the destruction of water supplies. Flying in a few tonnes of food may keep thousands alive temporarily, but many times as much clean water is still usually inadequate. However, Prof Peter Majewski of the...
By Mazurek, JM Wood, JM Occupational exposure to respirable crystalline silica occurs in construction, mining, manufacturing, and other industries and can result in silicosis and other lung diseases. Classic (chronic) silicosis results from exposure to relatively low concentrations of respirable crystalline silica for >/=10 years. Exposure to higher concentrations of silica for 5-10 years can cause accelerated silicosis, and symptoms of acute silicosis can sometimes develop within weeks of...
