Claims (6)

  1. 실리카원, 알루미나원, 알칼리원 및 테트라메틸 암모늄원 함유하는 출발혼합물을 가열하에 결정화하는 것으로 되어 있는 합성 마자이트의 제조방법에 있어서, 알칼리금속 규산염의 수용액, 알칼리금속 알루민산염의 수용액, 알칼리금속 수산화물의 수용액 및 테트라메틸암모늄 화합물을 혼합하고 그 혼합물을 묵혀서 얻은 투명한 액상물질을 미리 출발 혼합물속에 존재시키는 것을 특징으로 하는 합성 마자이트의 제조방법.
  2. 제1항에 있어서, 액상물질의 조성은 다음의 산화물 몰비 SiO2/Al2O3= 8 내지 25, M2O/Al2O3= 7 내지 30, H2O/M2O = 10 내지 14, 및 TMA/SiO2= 0.05 내지 0.25를 특징으로 하며, 결정화용 출발슬러리로서의 출발 혼합물의 조성은 다음의 산화물 몰비 TMA/SiO2= 0.02 및 0.04, SiO2/Al2O3= 5 내지 30, M2O/Al2O3= 0.5 내지 10, 및 H2O/SiO2= 10 내지 40(상기에서 M은 알칼리금속 양이온을 표시하고 TMA는 테트라메틸암모늄이온을 표시한다.)를 특징으로 하는 합성 마자이트의 제조방법.
  3. 제1항에 있어서, 알칼리금속 알루민산염의 수용액, 알칼리금속 수산화물의 수용액 및 테트라메틸암모늄 화합물을 먼저 서로 혼합하고 그런뒤 그 혼합물에 알칼리금속 규산염의 수용액을 혼가하는 특징으로 하는 합성 마자이트의 제조방법.
  4. 제1항에 있어서, 25 내지 50℃의 온도에서 교반하면서 겔상 고체물질이 형성되지 않는 시간동안 상기 혼합물을 묵히는 것을 특징으로 하는 합성 마자이트의 제조방법.
  5. 제1항에 있어서, 규소원으로서의 알칼리금속 규산염의 수용액 및 알루미나원으로서의 알루미늄함유 수용액을 실질적으로 일정한 비로 동시적 및 연속적으로 반응영역에 공급하여 무정형 알루미노규산염의 균질화합물을 제조하며, 투명한 액상물질을 무정형 알루미노규산염의 균질화합물에 혼가함으로써 출발 혼합물을 제조하는 것을 특징으로 하는 합성 마자이트의 제조방법.
  6. 제1항에 있어서, 결정화온도가 90 내지 140℃의 범위에 있는 것을 특징으로 하는 합성 마자이트의 제조방법.
