Foamed ceramic material and combined micro-through-hole foamed ceramic plate for sound barrier
The invention relates to the technical field of inorganic non-metallic materials, in particular to a foamed ceramic material and a combined micro-through-hole foamed ceramic plate used for a sound barrier. In the technical scheme provided by the embodiment of the invention, the foamed ceramic with high aperture ratio is prepared by adding a plurality of auxiliaries into the silicon nitride powder, the two foamed ceramic plates are prepared on the basis of the foamed ceramic powder, and the cavity is formed between the two foamed ceramic plates, so that the final combined micro-through-hole foamed ceramic plate for the sound barrier is formed. Good silencing treatment is carried out on a plurality of sound frequencies in a long frequency band.
本发明涉及无机非金属材料技术领域，具体涉及一种泡沫陶瓷材料及其用于声屏障的组合式微通孔泡沫陶瓷板。本申请实施例提供的技术方案中，通过在氮化硅粉料中添加多种助剂制备得到高开孔率的泡沫陶瓷，并基于泡沫陶瓷粉料制备得到两个泡沫陶瓷板并将两个泡沫陶瓷板之间设置空腔形成最终的用于声屏障的组合式微通孔泡沫陶瓷板，实现对于长频段内多个声音频率进行良好的消声处理。
