shenxing ceramic heating resistance ceramic insulator 95% alumina ceramic holder
1. Material & Grades
Alumina holders are fabricated from high-purity alumina ceramic, with different grades tailored for specific performance requirements:
• 95% Alumina (Al₂O₃): The most common grade. Offers an excellent balance of cost, strength (flexural strength ~280-320 MPa), density (~3.7-3.8 g/cm³), and thermal resistance (continuous use up to 1450°C). Ideal for general industrial applications.
• 99% Alumina (Al₂O₃): High-purity variant with superior electrical insulation (volume resistivity >10¹⁴ Ω·cm), enhanced thermal stability (up to 1600°C), and better chemical resistance.
• 99.5% - 99.7% High-Purity Alumina: Ultra-high grade for semiconductor, medical, and vacuum applications. Features maximum density (~3.96 g/cm³), minimal impurities, and exceptional performance at temperatures up to 1650-1800°C.

Alumina ceramic pipes are widely used in industries where traditional metal/plastic pipes fail to withstand wear, corrosion, or high temperatures. Abrasive Slurry Transport: Mining & Mineral Processing: For transporting tailings, mineral concentrates, and sand. Coal-Fired Power Plants: For conveying fly ash and bottom ash slurries. Steel Industry: For dust and fume extraction systems. Corrosive Chemical Handling: Chemical Plants: As liners or full pipes for aggressive acids and alkalis. Laboratory Equipment: For high-purity or high-temperature gas and fluid delivery. High-Temperature Applications: Thermocouple Protection Tubes: To shield temperature sensors in furnaces and kilns. Industrial Furnaces: As radiant tubes or for transporting hot gases. Welding Torch Nozzles: For their electrical insulation and heat resistance. Electrical Applications: Insulating Bushings and Sleeves: Where a pipe must provide a barrier that is both mechanically strong and electrically insulating.
