CoorsTek® AD-998 High-Alumina Rectangular Trays

CoorsTek AD-998 labware is made of 99.8%-pure aluminum oxide. Highly resistant to chemical attack, this alumina-ceramic labware is especially useful to chemists, metallurgists, and others involved in high-temperature work demanding contamination-free results. AD-998 labware is highly refractory, meant for use in reducing and oxidizing atmospheres. It is inert in hydrogen and carbonaceous atmospheres and offers high resistance to alkalies and other fluxes. Suitable for glass melting, including borosilicate glass. Recommended for use with refractory metals such as molybdenum, platinum, rhodium, tungsten, tantalum, and iridium. High-alumina labware temperature change rate should not exceed 150°C/hour.

CoorsTek AD-998 High-Alumina Properties:
• Maximum Use Temperature (No Load): 1750°C
• Thermal-Expansion Coefficient (25 to 1000°C): 8.0 x 10-6 / °C
• Compressive Strength: >300,000 psi
• Specific Gravity: 3.9 (Typical)
• Hardness: 79 on Rockwell 45N scale (9 on Mohs scale)
• Permeability: Gas-tight
• Water Absorption: None
• Chemical Tests: Hot concentrated sulfuric acid, 100°C
