Sound insulating, partitioning and enclosing ceramic element, has surface formed between external part and internal part of ceramic block, where ceramic block is formed with gaps and dense core

摘要

The element has a ceramic block whose internal part is partially filled with a heavy material, where the ceramic block is made of low-density clay. The ceramic block is divided into two external zones. The ceramic block is formed with gaps and a dense core. A surface is formed between an external part and the internal part of the ceramic block.
