· LaB4

LaB₄ is a lanthanum-boron ceramic compound belonging to the rare-earth boride family, characterized by a hexagonal crystal structure and extreme hardness. This material is primarily investigated in research contexts for high-temperature applications, cutting tools, and wear-resistant coatings, where its thermal stability and mechanical properties at elevated temperatures offer advantages over conventional carbides and oxides. While not yet widely deployed in high-volume industrial production, LaB₄ represents an emerging alternative in the rare-earth boride family for specialized applications demanding exceptional hardness and thermal performance in demanding environments.

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.
