Fused silica for precision casting (refractory)
Qmin-Sil is a product made from amorphous silica (SiO2) used for precision casting (refractory), produced from high-purity quartz ore sourced from China, using an electric melting method (with melting temperatures of 1800-2000°C). It is processed through dedicated equipment involving crushing, grinding, foreign matter removal, demagnetization, and sieving. The product is available in both granular and powdered forms.
