| titleOfInvention | Preparation method of alumina ceramic for automobile pressure sensor |
| abstract | The invention discloses a preparation method of alumina ceramic for an automobile pressure sensor, which comprises the following steps: A. mixing 95-97 wt% of alpha-Al 2 O 3 1-2 wt% of kaolin, 0.5-2 wt% of calcium carbonate, 0.5-1 wt% of silicon dioxide and 0.3-0.7 wt% of zirconium silicate are prepared into raw materials, and then PVA17-99 and n-octanol are uniformly mixed into the raw materials; B. ball milling; C. spray granulation; D. dry pressing and molding, and then sintering; E. vibrating and grinding; F. surface metallization and the like, wherein the aluminum oxide ceramic is adopted as a matrix; adding zirconium silicate; improving a ball milling mode; secondary metallization of the surface and the like to ensure that the density of the ceramic finished product reaches 3.69g/cm 3 The elastic modulus is about 310Gpa, the thermal expansion coefficient is about 5x 10-6/DEG C (from 25 to 500 ℃), and the flexural strength is about 288 MPa. |
