High temperature-resistant 96% alumina is used by Binzhou Aonuo New Material Technology Co., Ltd. to manufacture green (un-fired) ceramic tape which can be used in a variety of applications. This ceramic tape can be used in both the green (un-fired) state or with additional processing to produce hard-fired substrates.
The green ceramic tape is produced by using the Roll Compaction method. This allows the ceramic tape to be manufactured to precise thickness specifications. Tooling is then used to mechanically punch the ceramic tape, producing parts to the desired green size and shape. The tape parts are then fired by passing through a high-temperature kiln.
