| 摘要 |
The thermal spraying material consists of 85~96 weight% of silicon dioxide(SiO2), 1.0~3.0 weight% of aluminum oxide(Al2O3), 0.5-2.0 weight% of calcium oxide(CaO), 0.5~1.0 weight% of ferric oxide(Fe2O3) and other impurities, Its particle diameter keeps under 0.1mm. Therefore, the thermal spraying material gets excellent fusion state, produces no gas bubble and improves the life span of a furnace.
