Alumina Ceramics Density

At 25o c its density is 3 965 g m3 at standard atmospheric pressure.

Alumina ceramics density.

Typical alumina al 2 o 3 99 5 properties. Purity levels are available from 85 through 99 9. Alumina is the most well known and most commonly used fine ceramic material. This material has superb material characteristics such as high electrical insulation high mechanical strength high wear and chemical resistance.

Maximum operation temperature 1 000 to 1 200 c. Alumina represents the most commonly used ceramic material in industry. In the national standard gb t5593 1999 the bulk density of 95 alumina ceramic is required to be 3 60 g cm3 or more. Alumina ceramics al o alumina or aluminium oxide al 2 o 3 is a major engineering material.

Ceramics made with p172hpb have an exceptional bending strength and corrosion resistance at high temperature. The density of alumina ceramics varies according to the temperature. Al 300 97 6 alumina this is a top quality alumina ceramic of 97 6 al 2 o 3 content widely used for high integrity components where its exceptional electrical and thermal properties are essential to operational stability and reliability. Bulk density the bulk density of 95 alumina ceramics has a great relationship with the choice of raw materials and the manufacturing process.

This material has an excellent cost to part life performance record. Alumina can be produced in a range of purities with additives designed to enhance properties. Density 3 6 to 3 95 g cm 3 hardness 15 to 19 gpa compressive strength 2 350 to 4 000 mpa mechanical strength 350 to 630 mpa volume resistivity 1 10 14 ωcm 25 c thermal conductivity 12 to 39 w m k high abrasion and wear resistance. This ready to press powder is recommended for high alumina content ceramics 99 8.

It has the same sintered crystal body as sapphire and ruby. A higher fired density than p172lsb is achievable. P172hpb p172sdp ready to press alumina p172sdp is a spray dried p172lsb. It provides superior abrasion high temperature and chemical resistance and is also electrically insulating.
