Calcium carbide slag is industrial waste residue produced after calcium carbide hydrolysis to prepare acetylene, mainly composed of calcium hydroxide. It features strong alkalinity and low cost, which can replace quicklime for environmental protection desulfurization, building materials production, sewage treatment and roadbed backfilling to realize solid waste recycling.
| Chemical Name | Mixed Waste Residue Mainly Containing Calcium Hydroxide |
| Chemical Formula | Main Component Ca(OH)₂ |
| CAS No. | 1305-62-0 |
| Appearance | Grayish white fine powdery wet residue |
| Density(20℃) | About 2.24g/cm³ |
| Solubility | Slightly soluble in water, aqueous solution strongly alkaline |
| Stability | Easy to absorb moisture and agglomerate in open air, easy to turn into calcium carbonate by absorbing carbon dioxide, lasting stable alkalinity |
Used as flue gas desulfurizer for power plant boilers, raw material for aerated brick production, acid-base neutralizer for industrial wastewater, roadbed cushion filler, acid soil conditioner, raw material for light calcium carbonate preparation and mine fireproof sealing material.
Stack centrally in open yard with rainproof and anti-seepage covering, avoid lye outflow caused by rain erosion, keep away from acidic material yard, turn regularly to prevent hardening and store separately by dry and wet state.
