K2Al2B2O7
ceramic· K2Al2B2O7
K2Al2B2O7 is a potassium aluminum borate ceramic compound belonging to the borate ceramic family, which combines the thermal and chemical stability of borates with aluminate phases. While primarily encountered in materials research and specialized applications, this compound is of interest in glass and ceramic formulations, refractories, and high-temperature applications where borate ceramics provide thermal shock resistance and low thermal expansion. Its value lies in the borate family's ability to lower melting temperatures and improve sintering characteristics compared to conventional alumina ceramics, making it potentially useful for cost-effective high-temperature composite systems.

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.
