What are Engineering Ceramics?
Engineer ceramics are components of ceramic to provide solutions for engineering conditions with special requirements.Ceramics offer many advantages compared to other materials. They aremore heat and corrosion resistant than metals or polymers; less dense than most metals and their alloys; and their raw materials are both plentiful and inexpensive. These good properties facilitate their use in many different product areas.The common engineer ceramics include alumina ceramic, steatite ceramic, zirconia ceramic, cordierite ceramic and titanium ceramicetc.If you are looking for a material that has a longer working life and can stand up to wear, corrosion and high temperature, the engineering ceramic is the answer.
