Enhancement and explosion-proof mechanism of aluminum
· Nowadays BF iron runner castables are mainly composed of the Al 2 O 3 –SiC–C (ASC) system. Raw materials of typical ASC castables include alumina silicon carbide and carbon and a binder such as Al 2 O 3 powder SiO 2 powder or aluminate cement. Alumina is typically the main component in BF iron runner castables.

Effect of B4C on the properties and microstructure of
· The effect of B 4 C addition (0.5 wt 1 wt 1.5 wt 2 wt ) on properties and microstructure of Al 2 O 3-SiC-C (ASC) based trough castables was studied in this paper.The results showed that the bulk density of samples after firing at 1450 °C decreased when the addition of B 4 C was over 1 wt . The cold modulus of rupture of samples improved significantly with the addition of B 4 C

C Cement for ASC Castable
· Graphite carbon black or pitch are added for C. Of course the effect in castable is according to the addition and types of carbon raw materials. Generally C is added as pitch based spheres or coke and addition is about 5 . 2)High alumina cement and pure calcium aluminate cement are used for the binding agents for Al2O3-SiC-C castable.

The use of graphite in the refractory industry
Refractory products are nonmetallic ceramic materials (may contain metals) that have a C. OR Refractories are products which are installed whenever high temperature ( 6002 000 C) exists. Refractory materials are based on 6 oxides Al 2 O 3 SiO 2 MgO CaO Cr 2 O 3 ZrO 2 their compounds and often in combination with carbon.

Sample PreparationNon-HF digestions for refractory
We suggest using a Na 2 CO 3 fusion in a platinum crucible at 1000 C for these samples. For SiC (silicon carbide) 40 mg of sample and 2 g Na 2 CO 3 is recommended. The same should be fine for alumina (Al 2 O 3).There are numerous fusion types to choose from but we suggest Na 2 CO 3 fusions as they are effective safe and high purity sodium carbonate is readily available.
