4. Large stock and deliver quickly.
The alumina ceramic boat, through its outstanding physical and chemical properties and continuous material innovation, has become a key component in high-end industrial fields. It especially demonstrates irreplaceable advantages under harsh working conditions. With the progress of manufacturing technologies (such as additive manufacturing), its application scope is being further expanded to cutting-edge fields like aerospace.
Applications of Alumina Ceramic Boat
1.The alumina ceramic boat is used in reaction vessels for strong acids/alkalis to avoid the contamination of metal ions and improve the product purity.
2. As a wafer carrier (Boat), the high-purity alumina ceramic boat can prevent the contamination of silicon wafers, and its high-temperature resistance characteristic supports the CVD/PVD processes.
3. Alumina ceramic boat is used for the transfer and casting of molten metals (such as aluminum and copper) to prevent the adhesion of metals.
4. The alumina ceramic boat is suitable for corrosive environments such as chemical reaction vessels and electroplating tanks.

Factory Equipment
Slip casting moulding: Inject the prepared slurry into the gypsum mold and let it stand for a period of time to allow the gypsum mold to absorb moisture. The slurry forms a uniform body on the inner wall of the mold.
Injection moulding: Inject a slurry containing paraffin into a metal mold at a certain temperature and pressure, and after the body cools and solidifies, perform demolding to prepare ceramic bodies.
Extrusion moulding: Suitable for long tube products, the powder is extruded into shape through an extruder.
