Quartz Ceramic Collecting Balls Fused Silica Products Picking Balls Furnace Parts for Melting Glass
Descrição do produto
1.Quartz products for glass melting are made of fused silica.
2. Quartz products can withstand temperatures up to 1650 °C.
3. Chemical composition: SiO₂ 98.25%, Al₂O₃ 0.15%, Fe₂O₃ 0.13%
características do produto
1. The quartz ceramic does not deform easily in a pot, even during long melting cycles.
2.Quartz can withstand rapid heating and cooling cycles.
3.Because quartz is highly pure and inert, it reduces the risk of refractory particles contaminating the glass.
4.Quartz erodes slowly; it will provide a long service life.
Introduction to Quartz Products
Quartz ceramic is also referred to as fused silica ceramic or sintered fused silica products.
It exhibits excellent thermal shock resistance, low thermal conductivity, a low coefficient of thermal expansion, high-temperature resistance, and exceptional thermal stability, making it particularly ideal for applications in glass furnaces and glass manufacturing.
Quartz ceramic products offer the advantages of corrosion resistance, erosion resistance, zero contamination to glass products, and a long service life.
