Embodiment 1
[0059] Example 1: A method for preparing a silicon-based ceramic core, comprising the steps of configuring and mixing powder materials, preparing slurry, pressing and molding, and sintering.
[0060] The steps of powder preparation and mixing include weighing quartz glass powder, zircon powder, and cristobalite powder in a certain proportion by mass and mixing them to obtain a mixture of quartz glass powder, zircon powder, and cristobalite powder;
[0061] The step of preparing the slurry includes adding a plasticizer composed of paraffin wax, beeswax, and high-pressure polyethylene in a certain proportion by mass, heating and melting the plasticizer, and adding quartz glass powder and zirconium powder prepared in the steps of powder configuration and mixing. Powder, cristobalite powder mixture, stir to obtain slurry;
[0062] The step of pressing and molding includes injection molding the slurry prepared in the step of preparing the slurry, so that it forms an embryo body o...
Embodiment 2
[0083] Example 2: The difference from Example 1 lies in the preparation of the ceramic core powder formula, the percentage by weight is: 93% fused silica glass powder; 5% zircon powder; 2% cristobalite powder. Taking 10kg of prepared ceramic core powder as an example, the ratio of prepared ceramic core powder is: 9.3kg of quartz glass powder, 0.5kg of zircon powder, and 0.2kg of cristobalite powder.
Embodiment 3
[0084] Example 3: The difference from Example 1 lies in the preparation of the ceramic core powder formula, the percentage by weight is: 93% fused silica glass powder, 4% zircon powder, and 3% cristobalite powder. Taking 10kg of prepared ceramic core powder as an example, the ratio of prepared ceramic core powder is: 9.3kg of quartz glass powder, 0.4kg of zircon powder, and 0.3kg of cristobalite powder.
