Applications of Advanced Ceramics in the Chemical, Plastics & Rubber

Anwendungen von Hochleistungskeramik in der Öl- und Gasindustrie

Advanced ceramics have emerged as indispensable materials across the chemical, plasticsund rubber sectors, thanks to their exceptional corrosion resistance, wear resistanceund high-temperature stability. From reactor linings in petrochemical plants to ceramic-coated rollers in polymer processing lines, these engineered materials optimize equipment longevity, improve process efficiency, and enable green manufacturing.

Great Ceramic provides precision-engineered ceramic components specifically designed for the chemical, plastics, and rubber industries. These technical ceramics offer unmatched wear resistance, thermal stability, chemical inertness, and electrical insulation, making them essential for upstream, midstream, and downstream applications.

Why Use Advanced Ceramics?

Advanced ceramics are engineered materials characterized by high purity, controlled microstructures, and superior properties compared to traditional ceramics. Key features include:

Many industrial chemicals are highly corrosive and reactive with metals or polymers. Advanced ceramics like alumina (Al₂O₃), silicon carbide (SiC), and zirconia (ZrO₂) offer outstanding chemical stability, even in strong acids, alkalis, and solvents.

Processes in chemical and rubber manufacturing often involve elevated temperatures exceeding 1000°C. Ceramics such as silicon nitride (Si₃N₄) und Aluminiumnitrid (AlN) maintain their structural integrity at high temperatures, outperforming metals and engineering plastics.

Many processing steps—like mixing, extrusion, and pumping—create abrasive conditions. Ceramic components such as valves, seals, bushingsund liners offer extended service life under these conditions, significantly reducing downtime and maintenance.

In environments where electrical isolation is critical, ceramics like machinable glass ceramic (MGC) und boron nitride (BN) provide both thermal and electrical insulation, protecting equipment and ensuring operational safety.

These attributes make advanced ceramics indispensable in roles where metals or polymers fail—particularly in corrosive, abrasive, or high‐temperature environments.

benefit:

  • High temperature tolerance (up to 1,600 °C)

  • Chemical inertness against acids, alkalis, and solvents
  • Exceptional hardness and wear resistance, extending equipment life
  • Low thermal expansion and high thermal shock resistance
  • Electrical insulation or semiconductor behavior for sensors

Key Applications

In the Chemical Industry

  • Challenge: Reactors and distillation columns are susceptible to corrosion in strong acid and alkaline environments.
  • Solution: Using alumina ceramic linings or silicon nitride coatings can extend service life by 5–10 times.
  • Example: A chemical plant replaced its reactor lining with stainless steel Al₂O₃ ceramic, extending equipment downtime and maintenance intervals from 6 months to 18 months, significantly reducing operating and maintenance costs.

  • Challenge: Traditional metal seals wear rapidly in high-temperature, high-pressure, and corrosive environments.
  • Solution: Aluminum nitride (AlN) ceramic seals offer high-temperature resistance (up to 1,400°C) and chemical resistance.
  • Advantages: Stable sealing performance, reduced leakage risk, and improved production safety.

  • Application: Ceramic sensor probes for chemical online monitoring instruments offer the dual advantages of high-temperature insulation and chemical resistance, making them suitable for smart manufacturing and Industry 4.0.

in the Plastics Industry

  • Challenge: High-viscosity plastics create high friction between the screw and barrel, easily leading to equipment wear and production line downtime.
  • Solution: Spraying a silicon carbide (SiC) or boron carbide (B₄C) ceramic coating on the inner wall of the screw barrel reduces friction and extends equipment life.
  • Result: Screw wear is reduced by 60%, and routine maintenance costs are reduced by 40%.

  • Advantage: Using silicon nitride ceramic molds, with their high thermal conductivity and wear resistance, significantly improves the surface quality of plastic parts and production stability.
  • Case Study: An automotive interior parts manufacturer adopted Si₃N₄ ceramic molds, achieving a 15% reduction in molding cycle time and a 30% drop in defective product rates.

  • Requirement: Precise temperature control and fast response.
  • Solution: Aluminum nitride (AlN) ceramic heater rods offer high thermal conductivity (>140 W/m·K) and excellent electrical insulation, enabling rapid temperature ramping and stable temperature control.

in the Rubber Industry

  • Scenario: In oil and natural gas transportation, seals are subject to high pressure and chemical corrosion.
  • Solution: Ceramic/elastomer composite seals leverage the ceramic surface hardness and corrosion resistance to extend seal life by 2–3 times.

  • Requirement: Resist corrosion and wear from vulcanizing agents during high-temperature vulcanization.
  • Solution: Silicon nitride (Si₃N₄) or silicon carbide (SiC) linings improve wear resistance and anti-stick properties, ensuring product consistency.

  • Advantages: SiC ceramic rollers offer high surface hardness and excellent wear resistance, making them suitable for high-intensity mixing and reducing downtime for roll changes.
  • Case Study: After upgrading to ceramic rollers, a rubber products factory saw a 20% increase in production capacity and a reduction in maintenance intervals from 20 days to 60 days.
