通信装置
摘要：
本发明涉及一种利用频率在800MHz至3GHz的无线电波的通信装置，所述通信装置包括至少部分地暴露在所述通信装置的外部环境中的陶瓷外壳，在所述装置使用期间所述无线电波的至少一部分穿过所述外壳，所述外壳至少部分地由具有以下化学组成的烧结产品组成，诸如，以重量百分比且总量为100％计：32％≤ZrO2≤95％，1％
摘要（英）：

The invention relates to a communication device using radio waves with frequencies of 800 MHz to 3 GHz, comprising a ceramic cover at least partially exposed to the external environment of the device, at least one portion of said waves passing therethrough during the use of the device, said cover being at least partially made of a sintered product having a chemical composition such as, by weight and for a total of 100 %: 32 % <= ZrO2 <= 95 %, 1 % < Y2O3+CeO2+Sc2O3+MgO+CaO, 0 % <= CeO2 <= 26 %, 0 % <= MgO <= 43 %, 0 % <= CaO <= 37 %, 0 % <= SiO2 <= 41 %, 0 % <= Al2O3 <= 55 %, 0 % <= TiO2 <= 30 %, 0 % <= lanthanide oxides, except for CeO2 <= 50 %, 0 % <= SrO <= 24 %, 0 % <= SiAlON compounds <= 50 %, and other compounds <= 15 %.
