“…Therefore, further research was carried out to synthesized ␣-cordierite using mainly talc and kaolin by crystallization glass methods in order to decrease the melting temperature of glass and crystallization temperature of ␣-cordierite without the addition of flux, which would increase the CTE values. Even though, there are many studies on the synthesize of ␣-cordierite using talc and kaolin as the starting raw materials together with other minerals such as magnesium compounds [39], silica, alumina [40], gibbsite [31,41], calcined alumina and fly ash [32], magnesium oxide [42], diatomite and alumina [36], silica, sepiolite and felspar [43], fly ash, fused silica and alumina mixture [33], alumina [44,45]; however, most of them following solid state reaction route, except two [1,10] used glass crystallization method.…”
