How to Select Ceramic Structural Parts: 4 Steps to Avoid Pitfalls

Ceramic structural components are one of the core parts of a piece of equipment; choosing the wrong one can lead to soaring costs and equipment failure. Don't panic! Master these 4 core steps, and even as a procurement novice, you can quickly match the right ceramic structural parts.

I. Understand the Demand | What Kind of Ceramic Structural Parts Does Your Working Condition Need?

1. How Harsh is the Working Environment?

High temperature? Corrosion? Wear? The working environment determines the type of structural ceramic material.

• High-Temperature Environments: If the equipment operates long-term above 800℃ (such as high-temperature furnaces, electronic high-temperature equipment, or engine hot-end components), you can choose Alumina, Zirconia, Yttria, Silicon Carbide, and Silicon Nitride ceramics, which can withstand thermal deformation and ensure structural stability. In electronic equipment heat-dissipation applications, Aluminum Nitride ceramics can effectively dissipate heat.
• Corrosive Environments: For regular contact with strong acids, strong alkalis, or salt spray (such as chemical reactors or marine equipment), Alumina, Zirconia, Silicon Nitride, and Silicon Carbide ceramics are excellent choices due to their strong chemical stability.
• Wear Environments: For high-friction or impact-load scenarios (such as bearings or cutting tools), you can choose Alumina, Zirconia, Silicon Carbide, or Silicon Nitride ceramics. They possess high hardness and good toughness.

2. Should Core Performance be "Stable" or "Extreme"?

Clarify the performance focus of the ceramic components for your equipment to avoid "using a sledgehammer to crack a nut" or "under-powering a heavy load."

II. Calculate the Price | How to Plan Your Procurement Budget for Ceramic Structural Parts?

Price differences for ceramic structural parts are significant. Choose a cost-effective solution based on your budget.

Economic Grade: Alumina Ceramics

Alumina ceramics have abundant raw materials and mature processes, resulting in low unit prices. They are suitable for conventional electronic insulating parts and wear-resistant liners.

Mid-Range Grade: Aluminum Nitride / Zirconia Ceramics

Aluminum Nitride offers excellent thermal conductivity for cooling; Zirconia is hard and tough, suitable for high-end bearings and medical components.

High-End Grade: Silicon Nitride / Silicon Carbide Ceramics

These withstand harsh conditions such as extreme heat and corrosion. However, complex preparation and high purity requirements keep costs high.

Specialty Grade: Yttria Ceramics

Yttria ceramics are used in specialized fields like optics and high-temperature detection. Despite the high cost, their unique performance is irreplaceable in specific high-end scenarios.
