95%-99.8% Alumina Ceramic Mounting Block with Countersunk Through Holes

• Excellent electrical insulation: High resistivity, suitable for high-voltage applications and the isolation of heating elements.
• High-temperature resistance: Remains stable over long periods in oxidizing atmospheres; does not oxidize or soften.
• Corrosion resistance: More stable than metals when exposed to most acids, bases, and corrosive gases.
• High hardness and wear resistance: Suitable for environments involving friction or exposure to abrasive powders.
• Good dimensional stability: Resists deformation at high temperatures, making it ideal for precision positioning.

Used as insulating mounts for heating wires or strips, or as supports and spacers for thermocouples within furnaces, preventing short circuits and oxidation caused by metal-to-metal contact.

Used for terminal blocks, electrode supports, high-voltage isolation blocks, and internal fixtures for power supply units, leveraging the material's insulating and heat-resistant properties.

The two holes can accommodate thermocouples or electrical leads; the component serves as a mounting base or probe fixture for temperature sensors, providing electrical insulation and media isolation.

When made from high-purity alumina, these components serve as insulating supports, positioning blocks, or corrosion-resistant fixtures within vacuum chambers—critical for minimizing metal impurities and preventing contamination. 

5. Chemical Processing and Electroplating Equipment

Used for supports, mounting blocks, flow-guiding components, and pump/valve accessories in corrosive environments; offers superior resistance to acids, alkalis, and corrosive media compared to metals.

Suitable for use as wear-resistant pads, guide blocks, pressure blocks, or liners for powder-handling equipment; helps reduce metal-on-metal wear and metallic contamination.

Used for insulating blocks in battery testing fixtures, support blocks for high-temperature tooling, and isolation components in electrolyte-exposed environments (specific chemical compatibility and temperature limits must be verified).
