多孔氧化鋁陶瓷基板
多孔燒結的氧化鋁基板,在脫脂及燒結過程中可用來支撐生胚陶瓷用,由於多孔陶瓷具有高的孔隙在有機高分子燒除過程中尤顯現出優良空氣透過率。
Tai-Yiaeh provides high technology porous, fired alumina substrate used to green ceramic part during binder burn out and sintering process. It shows good gas permeability during organic binder removal due to high porosity and good thermal shock.

多孔氧化鋁陶瓷坩堝
高技術耐熱震陶瓷坩堝,內部係由體積比百分之30 至40 之類樹枝狀孔隙結構而成,表層則是較為緻密的燒結體。多孔結構對於熱震效應的緩衝和微細裂縫的傳導抑制,具有非常明顯的效果。因此,多孔陶瓷坩堝與一般泥漿澆鑄或是模具加壓成型所生產的陶瓷坩鍋比較起來,它的使用壽命可以更長久。
Tai-Yiaeh provides high technology ceramic crucibles with superior thermal shock resistance. Almost 30-40 vol% dendrite-like pore constitution establishes the interior of ceramic crucible; however, a rather dense structure forms the surface. The pore structure is very useful to be a buffer medium for thermal shock damaging and micro crack propagating. Comparing to those crucibles made by slip casting or mold pressing, Porous Ceramic Crucibles have longer performance lifetime.
