Strict Quality Control of Kerui Ceramic Fiber Products

Raw Material Pretreatment

High-purity cordierite, mullite, or silicon carbide powders meet industry standards. They are screened for purity and size.

Molding Process

The raw materials are dry pressed or slurry cast. Critical parameters include mold design (±0.1 mm tolerance) and demolding time (6-24 hrs) to prevent warping.

Drying

After drying, the green body is pre-fired at 800-1000℃ to remove organic matter and crystal water. This helps to ensure structural integrity.

Sintering

The firing temperature is between 1200-1600℃. The temperature curve is precisely controlled to avoid decomposition of cordierite.
