Benefits of ceramics in engineering?

  1. Jan 13, 2005 #1

    I've recently read about the material used for engineering, ceramics. What are the actual engineering benefits of using ceramics instead of titanium? Are there any other materials stronger than ceramics?

    Well, they are two different things and not necessarily related. Ceramics are hard and can withstand high temperatures, so you generally use them when you are looking for those properties - ovens, cookware, dishes, space vehicles, etc.

    Also, being hard isn't quite the same thing as being "strong." Titanium is stronger than most (all?) ceramics. Also, ceramics are usually quite brittle.

    Ceramics benefit from being harder (be careful with using the word 'stronger'), than many metals. They are also generally more resistant to temperature and corrosion.

    The drawbacks often relate to ceramics being much more brittle than metals. As a result, ceramics are very difficult to machine which is a major engineering drawback.

    Ah, ok.

    Thanks for the clarification. :smile:

    Also, ceramics can be created in different colors where aesthetics at high temperatures are an issue. Such as in gas fireplace logs or decorative cookware.

    Ceramics are also great insulators with very low conductivity (both heat and electrical). Metals are the opposite.

    ... and never forget use as coatings, sometimes can even get the best of both.

    Ceramic magnets are non conductive, comparitively lightweight, high energy, and inexpensive to manufacture.
