Alumina — Specific Heat Determination. Presented in the figure is a specific heat test result for a polycrystalline alumina sample between room temperature and 1600°C. Additionally shown are literature values for pure alumina. It can clearly be seen that there are no significant differences between the literature values and the test results.
Alumina Machining. Alumina can be produced in a wide range of purities with additives designed to enhance its properties. Typical purities range from 90 to 99.9% although Precision Ceramics generally works with 99.7% material. It can be injection molded, die pressed, isostatically pressed, slip cast, and extruded.
Specific surface areas and BJH adsorption cumulative surface area of pores of HA particles were measured using the BET method (ASAP 2020, American). To investigate the effect grinding on the hydration speed of HA, hydration heat curves of HA pastes with a deionized water/HA ratio of 1:1 were measured by a semi-adiabatic method at 30 °C.
