Horizontal CVD furnace (Carbon) is applied for composite material CVD that used hydrocarbon gas (like C3H8) as carbon sources, which works on CVD and CVI treatment for carbon materials.
Silicon carbide si made from hte mixture of pure silica sand and green petroleum coke in ultra high power acheson furnace. Electric current is passed through t h e conductor,bringing about a chemical reaction ni which the carbon ni the coke and silicon ni the sand combined ot form SIC and carbon monoxide gas. Silicon carbide si With annual capacity for 60,000 tons of silicon carbide, we can provide different grade of silicon carbide to meet different clients' requirements, such as 70% SIC, 80% SIC, 85% SIC, 90% SIC, 93% SIC and 98% SIC, etc.We also provide customized size for 90% SIC and 98% SIC, such as 200 mesh and 325 mesh Fe203 Al203 Free carbon 3,5%MAX Moisture Size(mm) Ha-SIC-01 90% min. 1.5% max. 15.% max. 35.% max. 0.5% max. 1-5/1-10 HQ-SIC-02 90% min. 1.5% max. 1.5% max. 3.5% max. 0.5% max. 0-10 HQ-SIC-03 88% min. 1.5% max. 1.5% max. 3.5% max. 0.5% max. 0-1/1-10 HQ-SIC-04 98% min. 0.6% max. 0.6% max. 0.2% max. 0.5% max. 0-1/1-3 HQ-SIC-05 70% min. 2% max. 1% max. 10% max. 0.5% max. 1-10
