Quartz (Q100)

Prod­uct Q100 consists of high-purity, sintered quartz (SiO₂), distin­guished by its excep­tional phys­i­cal and chem­i­cal prop­er­ties. Quartz, account­ing for approx­i­mately 12 wt.% of the Earth’s crust, is the second most abun­dant mineral and has long served as an indis­pens­able raw mate­r­ial in the manu­fac­ture of tech­ni­cal ceramic compo­nents. In partic­u­lar, quartz plays a central role in the produc­tion of precise and highly durable parts such as crucibles, firing trays, tubes, and plates, owing to its unique combi­na­tion of ther­mal stabil­ity, chem­i­cal resis­tance, and mechan­i­cal strength. The ceramic matrix of Q100 is based on sintered high-purity quartz, exhibit­ing near-complete crys­tallinity and being free of signif­i­cant impu­ri­ties. This level of purity is crit­i­cal to the material’s excel­lent ther­mal shock resis­tance (TSR). The abil­ity to with­stand rapid and severe temper­a­ture fluc­tu­a­tions with­out crack­ing or struc­tural defor­ma­tion makes quartz ceram­ics espe­cially suit­able for demand­ing appli­ca­tions. This is partic­u­larly true for use in induc­tion furnaces, as found in modern melt­ing systems from lead­ing manu­fac­tur­ers such as Bego, Linn, Heraus, and Manfredi, where fast heat­ing and cool­ing cycles are routine. Further­more, the mate­r­ial demon­strates remark­able chem­i­cal resis­tance to a wide range of metal melts, includ­ing iron, copper, and precious metal alloys, as well as to corro­sive and aggres­sive chem­i­cal envi­ron­ments. This prop­erty is espe­cially impor­tant for metal­lur­gi­cal and chem­i­cal processes in which quartz crucibles and other ceramic furnace components—such as firing trays and pour­ing chan­nels, are employed. The inher­ent resis­tance to corro­sion and chem­i­cal attack helps mini­mize mate­r­ial degra­da­tion, thereby signif­i­cantly enhanc­ing process stabil­ity and prod­uct qual­ity. With over 35 years of expe­ri­ence in the devel­op­ment and produc­tion of quartz and quartz compos­ite mate­ri­als, GTS possesses exten­sive exper­tise in mate­ri­als tech­nol­ogy and appli­ca­tion engi­neer­ing. Our compre­hen­sive data­base of mate­r­ial char­ac­ter­i­za­tions, process para­me­ters, and empir­i­cal data enables precise customer consul­ta­tion. This allows us to offer tailored solu­tions opti­mally aligned with the specific require­ments of indi­vid­ual melt­ing systems, includ­ing those of Bego, Linn, Heraus, and Manfredi. In addi­tion to the funda­men­tal mate­r­ial qual­ity, we provide the option to apply special­ized func­tional coat­ings to quartz crucibles, such as zirco­nium oxide (ZrO₂) or yttrium oxide (Y₂O₃). These coat­ings act as a barrier against unde­sir­able chem­i­cal inter­ac­tions between the ceramic mate­r­ial and the metal melt, reduc­ing wear and signif­i­cantly extend­ing the service life of the crucibles. More­over, these coat­ings contribute to mini­miz­ing cont­a­m­i­na­tion in the melt, thereby ensur­ing consis­tently high prod­uct qual­ity in demand­ing indus­trial melt­ing processes.
