## Manufacturing Process of Ceramic Balls
### 1. Raw Material Preparation
The production of ceramic balls begins with the selection of high-quality raw materials. Common ceramic materials used include:
– Alumina (Al2O3)
– Zirconia (ZrO2)
– Silicon nitride (Si3N4)
– Silicon carbide (SiC)
These materials are carefully measured and mixed with binders and additives to create a homogeneous mixture.
### 2. Forming Process
There are several methods to form ceramic balls:
– Dry pressing: Powder is compressed in spherical molds
– Isostatic pressing: Uniform pressure is applied from all directions
– Extrusion and spheronization: Material is extruded and then rounded
– Slip casting: Ceramic slurry is poured into spherical molds
### 3. Sintering
The formed green balls undergo sintering in high-temperature furnaces:
– Temperature ranges from 1400°C to 1800°C depending on material
– Process duration varies from several hours to days
– Controlled atmosphere (air, nitrogen, or vacuum) may be required
### 4. Grinding and Lapping
After sintering, the balls undergo precision finishing:
– Diamond grinding wheels achieve dimensional accuracy
– Lapping process improves surface finish
– Final tolerances can reach within 0.1 microns
### 5. Quality Control
Rigorous quality checks ensure product consistency:
– Dimensional measurements
– Surface roughness evaluation
– Hardness testing
– Roundness verification
