how much is zirconium vs silicon nitride ceramic ring

  • Ceramic bearings: zirconia or silicon nitride? | Bearing

    2020-3-6 · Typical ceramics that are used as bearing materials are silicon nitride (Si 3 N 4), and zirconia (ZrO 2). Silicon nitride is a very hard but also very light material. Boasting an excellent resistance to water, saltwater and many acids and alkalis, it also has a very wide temperature range and is suitable for use in high vacuum applications.

    2017-2-18 · They also have lower load ratings than steel bearings. Ceramic materials are much harder than steel but this also means they are more brittle, particularly silicon nitride. This reduces their load ratings. One benefit of full ceramic bearings is that they are highly corrosion resistant to seawater and most chemicals, including acids and alkalis.

  • Full ceramic bearings made from silicon nitride - SMB

    Pure silicon nitride (Si 3 N 4) is a material with great structural strength and resistance to high temperature. Processing this material is unfortunately difficult. A widely used technique to make silicon nitride more processable is the addition of a small quantity of certain metal oxides such as magnesium oxide (MgO) or aluminum oxide (Al 2 O 3). Since silicon nitride oxidizes, a minute layer of silicon oxide …
