ABSTRACT:
A process for producing an unsintered SiAlON material by carbothermic reaction without the use of contaminating transition metal oxides to increase the rate of reaction. The process includes providing small quantities of SiAlON crystals which seed the reaction. The phase of the SiAlON seed crystals will determine the phase of the SiAlON produced.
