Production of alumina ceramic boats
The alumina ceramic boat is made using slip casting technology.
Slip casting molding is actually a molding method that has been used for alumina ceramics for a long time. Because gypsum molds are mainly used, the cost is relatively low and it is also relatively easy to form. Even if the size and shape are complex, it is relatively easy to form. However, the key to slip casting molding is still the manufacturing equipment of alumina slurry. Normally, water is used as the main solvent, and then binders and adhesives are added. After sufficient grinding, air is discharged, and then it is poured into the gypsum mold because the capillary of the gypsum mold will adsorb water, and the slurry will quickly solidify in the gypsum mold. When conducting hollow slip casting, if the mold wall has requirements for the thickness of the adsorbent slurry, So it is necessary to pour out the excess slurry, but in order to reduce the amount of shrinkage of the billet, we should try to use a slurry with a higher concentration.
