1. Many alumina ceramic products used in life have certain requirements for hardness, so the hardness must be checked when accepting the alumina ceramic bars. In addition, the thermal conductivity and wear resistance of the alumina ceramic bars need to be checked. Because many of the environments where the alumina ceramic bars are used are wet, the corrosion resistance of the alumina ceramic bars also needs to be noted.
2. For alumina ceramic products, the fire resistance must be checked, and the fire resistance standard of alumina ceramic bars is basically above 1000 ℃, which is very important. In addition, when the alumina ceramic bars are in a high temperature state, the acid resistance of their corrosion resistance should be improved, which is also a major advantage of alumina ceramic products. Pay attention to this when checking.
3. In addition to the points just mentioned, the density of alumina ceramic products is often an important parameter to measure the quality. For alumina ceramic bars, the density will be very high, and the biological compatibility should also be good. These points need attention. In addition, the melting point of alumina ceramic bars is very high, because alumina ceramic products should be one of the materials with very high fire resistance in nature
