摘要
說明書
In some embodiments, the inorganic particle mixture includes a compound of bismuth, e.g. Bi2O3. The inorganic particle mixture may include at least 10 wt %, at least 15 wt %, at least 18 wt %, at least 20 wt % or at least 25 wt % of the compound of bismuth (calculated as Bi2O3). The inorganic particle mixture may include 60 wt % or less, 55 wt % or less, 50 wt % or less or 45 wt % or less of the compound of bismuth (calculated as Bi2O3). For example the inorganic particle mixture may include 20 to 50 wt % of the compound of bismuth (calculated as Bi2O3).
Alternatively, the compound of bismuth may be a bismuth nitrate, e.g. Bi5O(OH)9(NO3)4. The nitrate of bismuth (e.g. Bi5O(OH)9(NO3)4) may be used in an amount of at least 10 wt %, at least 15 wt %, at least 18 wt %, at least 20 wt % or at least 25 wt %. It may be used in an amount of 60 wt % or less, 55 wt % or less, 50 wt % or less or 45 wt % or less. For example it may be used in an amount of 20 to 50 wt %. In some embodiments, it may be preferable that Bi2O3 is used.
