Synthetic Cordierite
l Features
Low temperature glass frit powder usually has high thermal expansion, lead titanate which has negative thermal expansion is widely used to blend with low temperature glass frit to adjust its thermal expansion for ceramic substrate (PCB).
Duo to environmental issue, PbO is gradually no longer used.
Our synthetic cordierite has low thermal expansion with 100, 200, and 325mesh particle size, can be used as an ideal substitution of lead titanate.
l Application
Glass sealant for electronic materials and VFD, refractory ceramic materials.
