· JVASP-119171· LiAlSi3O8

LiAlSi3O8 is a lithium aluminosilicate ceramic belonging to the feldspar family, commonly known as spodumene in its natural form. This material is primarily valued in industrial applications where thermal stability and low thermal expansion are critical requirements, particularly in high-temperature cookware, laboratory equipment, and advanced composite systems. Its lightweight character combined with chemical durability makes it an alternative to traditional silicate ceramics in applications demanding thermal shock resistance and dimensional stability across temperature cycles.

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.
