DescriptionCertificationsDetailed Photos Fused Silica First
Grade (also known as A) High purity quartz stone in
Lianyungang and Xuzhou area was selected as raw material. After
pickling treatment, the crystalline silica was transformed into
amorphous silica with a small amount of impurity at 1800ºC high
temperature in the resistance furnace. After special mechanical
processing, screening, iron removal after the formation of blocks,
particles and powder products.Company Information:Xuzhou sainuo
quartz Co., Ltd. is located in Xinyi City, Jiangsu Province town,
is a company specializing in the production of fused quartz of
private technology companies. Polysilicon crucible with fused
silica level, fused silica nozzle with fused quartz secondary,
unshaped refractory materials used fused quartz secondary and a
variety of refractory materials with a fused quartz, whether all
the technical indicators and the real application effect at home
and abroad are first-class products, products in the domestic and
international have achieved good performance, the company is
currently with many well-known domestic enterprises and
