titanium is used in many sporting goods: tennis rackets, golf clubs, lacrosse stick shafts; cricket, hockey, lacrosse, and football helmet grills, and bicycle frames and components. although not a mainstream material for bicycle production, titanium bikes have been used by racing teams and adventure cyclists.
the most common use for portland cement is in the production of concrete. concrete is a composite material consisting of aggregate gravel and sand , cement, and water. as a construction material, concrete can be cast in almost any shape desired, and once hardened, can become a structural load bearing element.
until world war ii, uranium was mined primarily for its radium content; some carnotite deposits were mined primarily for the vanadium content. sources for radium, contained in the uranium ore, were sought for use as luminous paint for watch dials and other instruments, as well as for health-related applications, some of which in retrospect were certainly harmful.
bone cements have been used very successfully to anchor artificial joints hip joints, knee joints, shoulder and elbow joints for more than half a century.artificial joints referred to as prostheses are anchored with bone cement. the bone cement fills the free space between the prosthesis and the bone and plays the important role of an elastic zone.
uranium dioxide or uranium oxide, also known as urania or uranous oxide, is an oxide of uranium, and is a black, radioactive, crystalline powder that naturally occurs in the mineral uraninite. it is used in nuclear fuel rods in nuclear reactors. a mixture of uranium and plutonium dioxides is used as mox fuel. prior to 1960, it was used as yellow and black color in ceramic glazes and glass.
the largest use of stainless steel in cars is the exhaust line. environment protection requirements of reducing pollution and noise for the whole life of cars led to the use of ferritic grades typically aisi409/409cb in north america, en 1.4511 and 1.4512 in europe. they are used for collector, tubing, muffler, catalytic converter, tailpipe.
these vanadium carbides give the steel a very refined grain, further improving the sharpness and toughness. despite some difficulties with a consistent heat-treat, knifemakers use cpm s30v because its composition makes it easier to grind than other powder steels although the carbides still wear down the grinder belts considerably.
history. the industry can be traced back to an event where a single diamond blade mounted on a concrete saw was used to groove concrete pavement in the late 1940s. since that early tentative step, concrete grinding, grooving and texturing with diamond blades has developed into what is today a multimillion-dollar industry that is practiced worldwide.
cells use 5 and 2 formal oxidization state ions. vanadium redox batteries are used commercially for grid energy storage. vanadate can be used for protecting steel against rust and corrosion by conversion coating. vanadium foil is used in cladding titanium to steel because it is compatible with both iron and titanium. vanadium redox battery history characteristics chemistry occurrence productionwhite portland cement
white portland cement is also used in combination with inorganic pigments to produce brightly colored concretes and mortars. ordinary cement, when used with pigments, produces colors that may be attractive, but are somewhat dull. with white cement, bright reds, yellows and greens can be readily produced.
tantalum carbide, tac, like the more commonly used tungsten carbide, is a hard ceramic that is used in cutting tools. tantalum iii nitride is used as a thin film insulator in some microelectronic fabrication processes. the best studied chalcogenide is tas 2, a layered semiconductor, as seen for other transition metal dichalcogenides.
