摘要:
Articles and methods of making and using the articles are provided. The articles include inorganic agglomerates having an average dimension in a range from about 50 microns to about 2 mm. The porous agglomerates each include a network of carbon or silica, and metal oxide particles embedded in the network. Some agglomerates are capable of lowering a resonant frequency of an acoustic device when the resonant frequency is in a range from about 50 Hz to about 1500 Hz.
摘要(中):
提供制造和使用物品的文章和方法。 制品包括平均尺寸在约50微米至约2mm范围内的无机附聚物。 多孔聚集体各自包括碳或二氧化硅网络以及嵌入网络中的金属氧化物颗粒。 当谐振频率在约50Hz至约1500Hz的范围内时,一些附聚物能够降低声学装置的谐振频率。 p>
