Abstract
A finely divided inorganic filler material is a sintered composite which consists of larger macro-filler particles of glass and of smaller micro-filler particles of glass or ceramics partially covering the macro-filler particle and firmly connected to it by sintering. Plastic materials reinforced with the filler are distinguished by improved abrasion resistance.
