Fr this purpse, the ptimum cmpsitin is CaV 0.25 Sn and heating cnditin is at 1250 C fr 6 h f saking time. The samples were characterized by X- ray diffractin (XRD), the Furier Transfrm Infrared Spectrmeters(FT-IR), the Raman Spectrmeter, Scanning Electrn Micrscpe(SEM) and the UV/Vis spectrscpy. The substituted V in fr Sn was bserved t be quadrivalence. The analytical results f the synthesized pigment shwed the tetragnal crystal, a typical frm f Malayaite, and the particle size t be apprximately 5~10 µm. The clr in lime glaze added 12 wt% pigment was emerald green, and CIE Lab parameters are L =67.73, a = and b =9.28.

SEM 분석 결과 주된 입형은 Malayaite의 결정상으로 알 려진 tetragnal crystal형으로 나타났다. 유지시간이 6 h으 로 늘어났을 경우 결정이 성장한 것을 확인할 수 있으며, 12 h까지 유지시간을 늘렸을 경우 분해로 인하여 결정이 감소하는 것을 알 수 있다 결 1) Malayaite계 Emerald Green 안료의 최적 조성은 CaV Sn SiO 의 조성으로 나타났으며, 그 최적의 소 성 조건은 1250 C에서 6시간 유지하는 것이다. 이 경우 치환된 V in은 4가를 나타내었다. 2) 합성 안료를 SEM 분석한 결과 입형은 Malayaite의 전형적인 형태인 tetragnal crystal이었으며, 입경은 5~ 10 µm이었다. 3) 이 합성 안료를 석회유에 12 wt% 첨가하여 유약 실 험 한 결과, CIE L =67.73, a = 12.39, b =9.28의 수치를 나타내었으며 Emerald Green으로 발색하였다 Fig. 8.
