ABSTRACT:
A method of making a ceramic burner head includes the steps of forming a positive mold that conforms to the shape of a burner head and providing a partition plate to the positive mold; forming a negative plaster mold by the use of the positive mold; introducing a ceramic slurry into a mold cavity of the negative mold; causing the ceramic slurry in contact with a surrounding wall that confines the mold cavity of the negative plaster mold to possess a layer of dried ceramic with a predetermined thickness, and to further possess a hollow portion that is confined by the layer of dried ceramic and that is filled with a non-dried ceramic; removing the negative plaster mold and providing the layer of dried ceramic with burner holes; and sintering the layer of dried ceramic to form the ceramic burner head.
