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:With previous coated ceramic flatirons that i‘ve used, the ceramic coating seems to wear off and fade.: they are coated ceramic plates. ceramic hair straighteners protect the hair using heat to lock in moisture and natural oils, creating a smooth polished effect with added natural shine. the ceramic should last approximately 12-18 months with average use. you must remember that they generate intense heat. the heat eventually effests the ceramic coating on plates (crystal coated or backed ceramic lasts the longest) and heating elements eventually burn out. hope this helps x

Q:I‘m getting hair straighteners and i wanna know. I have thick frizzy hair!: simply fix it!just a bigger version of a pushbike tyre.if its tubless u ban get it ''bunged''

Q:Whats the best way to take care of a ceramic frying pan so it doesn‘t flake off material into your food?Whats the best way to keep it so it last a long time? When I cook eggs I don‘t use any oil I just put some water on the pan and cook my eggs that way, and when I do use oil I use a little and only for like chicken or burgers,: as mentioned before, enter diagonally and slowly. that should almost always do the trick

Q:Why alumina ceramics are acidproof and alkali resistant?: A-Al2O3, acid, alkali resistant, is a special atomic crystal

Q:Which one is a ceramic material1] quartz 2] silica3] clay 4] glassPlease mention what a ceramic material is.: Lighter weight. The Civil Air Patrol made a big mistake by ordering the Maul M-7 with tricycle gear, which greatly increased the weight, and made it bad for mountain flying, thus the aircraft didn't stay in the fleet for too long. The Maul M-7 taildragger was much lighter!

Q:Can polymer clay be used to model bigger sculptures ? If so, what‘s its advantage over other types of ceramic clays ? easier to carve the facial details maybe ? I just start to learn polymer clay and see if it is suitable to be used to my projects. I have been using both water and oil based clay for figure sculpting (about 1/4 to 1/2 of real human‘s height, which then casted to bronze or resin)and never thought about trying polymer type, as it seems to me polymer clay is popular only for hobbyists or those who make dolls and small sculptures. Is my assumption correct? Is there any professional sculptors using polymer to model for bigger pieces of projects before casting them to bronze or other materials ? Also is it true that polymer is better than other types of clay for detail carving in a small face ? Thanks in advance for any information you can share.: If I think of a figurine as being smaller than a Barbie doll and similar to the 6-8 costumed statues sold to display cute scenes or national costumes, I think you will find working directly in ceramic clay to drive you buggy. The commercial versions of these are almost always hollow, at least in the base and made of porcelain clay slip molded in plaster, cleaned up and fired at high temp and hand painted. More recent versions are cast resin, also in a mold. For direct work, I would say that polymer clay is a far more viable, and stronger once baked.

Q:I need art credit for high school but I don‘t want to take an extra elective. I am considering taking it over the summer but I‘m wondering if it is worth the Tu/Wed/Thu 9 to 1 for eight weeks and is the class easy and fun or boring and hard. Thanks.: Someone said don't attach to AC. He is DAMN right. I once tried it when I was kid. Blew up the house fuse :D Make sure you attach to some sort of battery. Car battery should work.

Q:what are the pros;cons: I have the ceramic kind and I really like them. In pictures you can't really see them as much so that's pretty nice. The only thing is the clear bands can turn yellow from eating things like soup, or drinking soft drinks, juice, tea, so you need to brush your teeth right after drinking those things. I noticed my bands were starting to turn yellow so I got an electric toothbrush, whitening tooth paste and whitening mouthwash and they went back to normal. So those are good things to have if you have ceramic braces.

Q:Yesterday I bought a ceramic teapot for my mother‘s birthday gift and while she was carrying out of the store, it fell down and the handle broke off and split in two parts. The pieces are glue-able because they are big enough, still, I am not sure what glue to use to put the pieces together since it needs to work on ceramic and it also has to be heat resistant. I was thinking of using epoxy glue and painting the scratched bits with nail polish. I also want to know if nail polish will work on epoxy or if the material would suck it off. Thanx!: I haven't heard of epoxy being used. Superglue is the best. Make sure you do a test run to put the parts together, then just glue one part of the ceramic and attach and hold firmly in place for a couple of minutes, job done. I don't know what affect the nail polish would have if any, I suspect once the glue has hardened it will be impervious to the acetylene in the polish.

Q:I‘m trying to find a really cool color that you can mix--(Under-Glaze) Anyone have any ideas for mixing colors together? Last project--I mixed 2 blues and black magic and it came out great--Anyone have any unique ideas? Thanks :): turn the dial to the marvelous ideal some circumstances to bathe it. Then supply up on your first decision. Then turn it to the left passing your 2nd decision yet supply up as quickly as you get to it the 2nd time. Then turn it to the marvelous ideal and supply up on the instant on your 0.33 decision. in case you fairly could do it speedy.you'll be able to preset your combination, yet i propose in basic words presetting your first 2 numbers. That way human beings walking interior the approach the halls should not be waiting to open your locker basically via pulling on the lock.
