95% alumina ceramic part

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.   Yixing Shenxing Technology Co., Ltd.
