Forming method for fine-structure beryllium oxide ceramic
The invention discloses a forming method for fine-structure beryllium oxide ceramic, and belongs to the technical field of manufacturing processes of electric character information technology equipment parts. The invention provides the forming method for the fine-structure beryllium oxide ceramic, which is relatively simple in process, low in cost, relatively high in yield and environment-friendly and non-toxic in forming mode. The forming method at least comprises the steps of pre-forging to obtain BeO powder, mixing and ball-milling to obtain BeO ceramic slurry with the solid content of 35-60 vol%, vacuum degassing and high-pressure injection molding to prepare a ceramic biscuit, and drying, degumming and sintering the ceramic biscuit, specifically, when the BeO ceramic slurry is prepared through mixing and ball-milling, the ratio of the BeO powder to deionized water to grinding balls is controlled to be 1: (0.2-1): (1-5), by adding a dispersing agent, a binder, a curing agent and a sintering aid at the same time, vacuum degassing is carried out on the BeO ceramic slurry under the vacuum degree condition of 0.01-0.1 MPa for 2-10 minutes, and a ceramic biscuit is dried after demolding comprises liquid rapid drying and heating slow drying.
