Abstract: PURPOSE: Provided is a preparation method of high strength artificial stone without crack using jade stone, which improves the product value and processing of jade by adding natural or artificial alkali metal oxides. CONSTITUTION: The preparation method of artificial stone using jade powder comprises the steps of: mixing 54-60% of jade powder(600 mesh) with 25-30% of artificial and 8-18% of natural alkali metal oxides such as mineral stone(mebanseok). sericite and germanium oxide; adding 8-11% of ethylene vinyl acetate(EVA); sintering as the following schedule, at 550-650°C for 25-35min to remove EVA and remained water, at 1300-1400°C for 3-5hrs. at higher than 1000°C for 2hrs. or more.

Abstract: 옥가루에화학약품이나천연물을첨가하여고온에서반응시켜가공소결함으로써옥의상품적가치와가공성을향상시킬수 있는옥가루를이용한인조석제조방법이개시된다. 본발명은옥가루에알칼리금속이온을함유한산화물을혼합하여 1차혼합물을생성하는단계, 1차혼합물에운반및 고온성형이용이하도록에틸렌비닐아세테이트(EVA) 유기물을혼합하여가압성형한후 건조시켜모양을성형하는단계, 성형된모양을고온열처리하여소결시키는단계로이루어진다. 본발명에따른인조석제조방법은옥가루와천연석분말혼합물에알칼리금속산화물이다량함유된물질을혼합하므로써고온에서소결체를생성할때 균열이생기지않으며고강도를갖게한다. 또한, 필요에따라천연석(맥반석, 맥섬석및 견운모, 게르마늄산화물) 분말을첨가하게되면옥가루의표면에서방사되는원적외선의선속을증대시킬수 있고보온효과가크다.
