Abstract
The aim of this study is synthesis of Amphibole Hornblende Asbestos from domestic ore （talc） and chemicals. To obtain a long fiber of asbestos, mole ratio of components, melting temperature of reaction mixture, rate of cooling of the melt and quenching temperature were varied and optimized. The resulting mixture was analyzed by X-Ray diffraction before and after treating with various decomposing solutions in an autoclave.
From the experiment, the following results were obtained;
1. Amphibole Hornblende Asbestos can be synthesized from domestic ore.
2. Optimum mole ratio is 1.25 Na2O∙0.5CaO∙0.2MgO∙MgF2∙Fe2O3∙8SiO2.
3. Optimum melting temperature is 1,250 ℃, optimum cooling rate is 2.5o/min, and optimum quenching temperature is 800 ℃.
4. Best decomposing solution is 2N-NaOH.
