· JVASP-154915· ThB4

ThB4 is a boride ceramic compound combining thorium and boron, belonging to the class of refractory borides known for exceptional hardness and thermal stability. This material is primarily of research and specialized industrial interest, valued in applications requiring extreme hardness, thermal shock resistance, and performance at very high temperatures where conventional ceramics degrade. ThB4 is typically considered for niche aerospace, nuclear, and ultra-high-temperature engineering contexts where its unique combination of hardness and refractory properties offers advantages over alumina, silicon carbide, or other standard ceramic alternatives.

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.
