manufacturing, marketing and serving. Because of leading technical capability in specialty field, advanced production equipment, unique production technology, complete examination device and scientific management system, in May 2005 BGR was issued national patent (No. ZL 2004 0001097.X).In 2006 BGR passed ISO 9001 inter2 national quality system certification.
Si3N4–SiC product is produced by advanced molding technology instead of traditional injection and pressed method. In this way BGR can make all kinds of ceramic parts with complicated shape. The product can be used for low-pressure die-casting, flue gas desulfurization, pump industry, mineral beneficiation, non-ferrous foundry, heat treatment, ceramic industry and so on. Product manufacturing standard follows ENTERPRISE STANDARD OF BEIJING GOLDEN RAINBOW SILICON NITRIDE COMPANY Q/FT JHD001—2007 issued by Beijing Fengtai District Bureau of Quality and Technical Supervision.

?While comparing the ceramic material property with other similar products in wide world, the average density exceed about 5% and cold modulus of rupture is as strong as twice times. Products used for non-ferrous foundry industry win good value by non-pollution metal liquid

Main technical personal worked for BGR had deeply researched Si3N4–SiC products for many years, and hold unique view in academia. Grinding experimental determination by Xi’an Jiao Tong University, the abrasion resistance of Si3N4–SiC material is 3.13 times as wearable as alloy chrome-molybdenum, and its hardness is only less than diamond and cubic crystal boron nitride which is Mohs 8.9.Desulfurizer nozzle can work last for more than 12 years; and ceramic slurry pump parts with excellent corrosion and abrasion resistance have more benefit than alloy chrome-molybdenum while used in tailing treatment, mineral beneficiation.
