DURMAX ALUMINA are manufactured for various applications for both artisanal and industrial use. We manufacture aluminium oxides and hydroxides, calcinated alumina and hydrated alumina, metallographic alumina, fire retardants, reactants for fire retardant treatments, special reactants for synthetic resins. Corundum and alumina for special ceramics. We manufacture high purity calcium fluoride and boron nitride. With an extended range of around 200 special alumina we provide bespoke manufacturing for customers worldwide. Certain alumina are for polishing in metallography and mineralogy as well as for all high precision polishing for all types of materials. Others (hydrated and calcinated) are used as special reactants in synthetic resins, rubber, etc. to improve their characteristics (fire, abrasion resistance; for their appearance, viscosity, lightness).
