Product Description

Zirconia is most famous high-performance material among all oxide ceramics. Ceramic components made out of Zirconia generally consist of Zirconia as basic material doped with some percentage of other oxides like Yttria (Y2O3) or Magnesia (MgO). Depending on doping material different material properties could be achieved because of influencing the Yttria's microstructure. The "ceramic steel" titled Zirconia is doped with Yttria forming an ultra-fine ductile structure with sub-micron grain formation leading to enormous bending strengths. Magnesia doped qualities are less strong also showing a coarser microstructure.

Common applications of Zirconia ceramics include extrusion dies, wire and pipe extension, guide and other wear rollers, pressure valves, and bearing materials.

Q:Are higher priced ceramic brake pads better than lower priced ones?: It depends on the specs. For average daily use, just go for the cheaper one. Unless you plan to put a lot of stress on your brakes, basically for racing applications. Using racing brakes on a commuter car can actually be bad, because some of the high end pads need to be heated up to work right. Which won't happen in a commute.

Q:I want to buy a couple of ceramic bowls to use for my dog's bowls. I want to paint some designs on the outside but I don't really know how I should go about doing it. Should I buy ceramic paint and then bake it afterwards? Or buy some other kind of paint and use a glaze? I am going to paint on the outside of the bowls and maybe on the inside so I would like it to be non-toxic. I also want it to last.: Paint the outside mostly green, with a tiny bit of white, and the inside watermelon pink. Talk to the people at a craft store, to be sure it will be safe for your dog. The kind you have to bake will be longer lasting.

Q:Ceramics are not crystalsTell me the exact answer. Thank you for your cooperation!: Most substance are crystals.Ceramic materials are generally crystals, because the ceramic contains many kinds of atoms, crystal structure is more complexIf you can't understand it, think about ruby.

Q:This is actually a material and manufacturing techniques question, but how do I attach ceramics to metal permanently, how does it come together and stay there? Is the ceramics heated up then poured or molded onto the metal piece and let cool? Any thoughts or speculations welcomed, thank you.: I would have to say that bonding the two materials would work best. One way is thermal spraying at high temperature as you suggest. Typically the metal base would be grit blasted to increase surface area for the spray to adhere. After spraying the ceramic coating the parts are introduced to a heat treat cycle to complete the bond. This bond becomes as permanent as possible. There is much more information on the web.

Q:I'm in high school and in a ceramics class.I want to make a bong. Of course.We have tons of freedom in the class, and the teacher likes me. We basically can make whatever we want as long as we're not wasteful.Except that my teacher is an ex-hippie. He loves to call everyone out on the bad bongs they make. He has a whole shelf of confiscated bongs. He shows them off and laughs at them.People have tried to be sneaky, but when he sees them working, he's always like, It's a bong. I'm not firing that, it's obviously a bong. One person even made theirs like a real heart, with two mouthholes and stuff, it looked pretty cool, but he confiscated it.He doesn't get angry; just amused. But he's definitely on top of things.Do you have any ideas how I can slip a bong past my teacher?As for all you people out there who will go down the, don't do drugs, or you're stupid, route, don't. I don't want to hear it; I've done my research, and besides, it's my business. Thanks.: One reason is driving too fast. 120 km per hour (U.S. readers: that is equivalent to 75 mph) is too fast for most roads in the world and probably all roads in India.

Q:We had picked a ceramic tile that was 1.20 a sq. ft. and ended up going with a porcelain tile that was 2.70 a sq. ft. . Is it really that much better?: When it comes to installing ceramic or porcelain tile in a shower, porcelain tile low absorption's rate make it a little bit better. It's low absorption rate also means the tile’s surface absorbs very little moisture, so spills that might otherwise leave a stain are easily wiped up with a damp cloth. Water and a mild soap are all that’s required for regular cleaning. - See more at:

Q:In other words, the clear braces.my brother says only adults can. But I have to get them and if I cannot get the clear kind I am going to smash a window because I have to look good!! Someone, help?: Ceramic braces are made for both upper and lower teeth. Most people only get clear on top and metal on the bottom, since you don't see much of the lowers when you talk or smile. Our office charges $350 per arch more for the clear braces. So if you want upper and lowers it's $700 more. Adults and teens can get clear braces if they choose. However, most teens get the metal braces. There is nothing wrong with getting all metal braces, I have 'em.

Q:What’s the difference between ceramic wool and rock wool?: Rock wool and ceramic wool are all used for insulation and the main difference between them is the working temperature. Comparatively speaking, rock wool’s working temperature is 650℃, lower than that of ceramic wool, which can reach 1450℃. But the thermal conductivity of rock wool is lower than that of ceramic wool. So, rock wool is usually used for wall insulation, and ceramic wool can be used in high temperature environments of all kinds of furnaces.

Q:good ceramic irons?: CHI irons are awesome but a bit expensive. Solano Sapphire Mini Iron won best hair straightener in Allure Magazine.

Q:The origin of ceramics: The Song Dynasty is the history of the development of ceramic peak, five kilns (Jun and Ru, officer, brother, set) featured ceramic Mingyangtianxia.Yuan, Ming and Qing three generations is a new stage of development Chinese ceramic art. Especially in the Yuan Dynasty occupies a space for one person in the Chinese green porcelain porcelain history, I porcelain development of the Ming Dynasty, has entered the golden age of live brilliant to porcelain. The kilns in Jingdezhen has become the "Poly" world kiln machine. The production of fine ceramics is the civilization of the Chinese nation ashamed treasure, we are proud of the Qing Dynasty. The origin of ceramic you call a wide and China ceramic output in great quantity.Since the second half of the nineteenth Century, especially after the Opium War, China's domestic ceramics handicraft industry began to decline. In short, China's ceramic production has 8000 years of history, during this period, China's potters and technology professionals, has created a miracle of ceramic art, ceramic and Yu Hai spread. The production of creation continuously, this is the law of historical development. But in recent years in the development of ceramic art ahead of China. Now it is time for us to revive the porcelain treasures!
