· NaB3O5

Sodium tetraborate (NaB3O5), commonly known as borax or a borax derivative, is an inorganic ceramic compound belonging to the borate family. It is widely used as a flux in metalworking, glass production, and ceramics manufacturing, where it lowers melting temperatures and improves material flow. In addition to industrial processing applications, borax compounds serve as precursors for borosilicate glasses and specialty ceramics, and are valued in detergents and flame-retardant formulations due to their thermal stability and chemical inertness.

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.
