· JVASP-62924· Al5BO9

Al₅BO₉ is an aluminum borate ceramic compound that combines aluminum oxide and boron oxide phases, forming a lightweight refractory material with moderate structural strength. This ceramic is primarily encountered in thermal insulation applications and high-temperature environments where corrosion resistance and dimensional stability are required, particularly in metallurgical furnaces, kiln linings, and specialized thermal management systems where conventional alumina-based refractories may be insufficient.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
