Abstract

The paper presents the results of mullite ceramics production using a plasma generator. Exposure of a briquette, produced from silicon-containing marshallit quartz powder and aluminum powder, to low-temperature plasma from a plasmatron has allowed producing a glassy ingot of silver color. X-ray phase analysis has revealed that the ingot contains amorphous and crystalline phases. The crystalline phase is mullite with orthorhombic syngony (D^{9}-{2h} = Pbam) and the chemical composition Al6.9Si1.22O4.85. A review of crystalline structures of mullite-based compounds has been carried out.
