1.good for casting gold,PT,SS 2.High purity 3.Heat preservation stability 4.Made of fused silica
Quartz crucibles are made of Fused silica powder,which is mainly applied in the field of jewelry casting industry
1. our industry can manufacture many sizes of quartz crucibles, used for jewelry ,dental,electron , chemical , glass and solar energy industry .
2. our industry use advanced methods of molding and shaping process to ensure that the product has no hidden defects . we use the latest testing equipment to test each crucible for supplying very good quality products to our customers .
3. we selected the highest purity fused silica as materials in which iron and basic metals are very low . meanwhile .
4. sample policy : 7 days when receive the design from customer
5.delievery time : 20---30 days when get the confirmation from customers
