Silica-based
SILICA-BASED MATERIALS
LithaCore 450 consists mainly of silica with additions of alumina and zirconia. It is used for the production of casting cores for investment casting. A typical application is the single crystal casting of turbine blades. This suspension is specially designed for the production of precise ceramic cores with intricate features and high accuracy. Sintered ceramic casting cores made of LithaCore 450 are characterized by minimal dilation up to 1500°C, high porosity, low surface roughness and very good chemical leachability after casting.
