Caustic Calcined Magnesia (CCM / Light‑Burned Magnesia) is produced by calcining natural magnesite ore at low temperature of 800‑1000 ℃.
Key Features：
It features high chemical reactivity and is easy to absorb moisture and hydrate, which is the key difference from dead‑burnt magnesia.
Available Grades：
CCM MgO 80%-95%
Main Applications：
‑ Bonding agent for magnesia‑based monolithic refractories: castables, ramming masses.
‑ Raw material for magnesium salt chemical industry, building materials, rubber, wastewater treatment and animal feed.
‑ Precursor material for producing high‑grade dead‑burnt magnesia.
Available Sizes & Packing：
Standard sizes:60-200mesh ,85%min passing through.
Sizes can be customized upon request.
Packing: 1/1.25 MT ton bags, 25 kg bags or on request.
COA certificate provided per batch.
