Quartz (Q100)

ca. 99% Quartz

Q100 consists of sintered ultra­pure quartz. Quartz is the second most commonly found mineral in the earth’s crust. Its chem­i­cal formula is SiO2. Quartz and quartz compounds are an impor­tant raw mate­r­ial in the ceram­ics sector for the manu­fac­ture of prod­ucts such as crucibles, anneal­ing dishes, pipes, plates and other moulded parts. Due to the good prop­er­ties of this ceramic, it is versa­tile and can be used in many areas. Its extremely high temper­a­ture change resis­tance enables such crucibles to be used in induc­tion melt­ing furnaces. Its resis­tance to many molten metals and other chem­i­cal substances is utilised in the produc­tion of anneal­ing dishes, cast­ing troughs and furnace compo­nents. GTS has been manu­fac­tur­ing prod­ucts from quartz and quartz compounds for over 25 years. An exten­sive data­base enables us to provide valu­able advice to customers on the opti­mal use of ceramic prod­ucts. Quartz crucibles can, for exam­ple, be coated with zirco­nium oxide or yttrium oxide in order to minimise the chem­i­cal reac­tions between ceramic and metal.
