GTS Keramik
Made in Germany

As one of Germany’s lead­ing manu­fac­tur­ers of indus­trial ceram­ics, GTS stands for the high­est qual­ity, tech­ni­cal inno­va­tion, and customized solu­tions in the fields of special ceram­ics and wear protec­tion tech­nol­ogy. Our exper­tise is based on decades of expe­ri­ence, inten­sive research, and contin­u­ous devel­op­ment of advanced ceramic mate­ri­als.

A central part of our prod­uct port­fo­lio consists of heat resis­tant ceram­ics used in a wide range of indus­trial high temper­a­ture appli­ca­tions. This includes, among others, induc­tion crucibles for melt­ing systems, specially designed for melt­ing lead, iron, gallium, copper, plat­inum, rhodium, zinc, and tin. These crucibles offer excel­lent ther­mal shock resis­tance, chem­i­cal dura­bil­ity, and mechan­i­cal stabil­ity even under extreme condi­tions.

Partic­u­larly note­wor­thy are our aluminum oxide crucibles, which we manu­fac­ture in both dense and porous qual­i­ties. Depend­ing on the appli­ca­tion, these vari­ants provide opti­mal prop­er­ties for vari­ous ther­mal processes from high purity labo­ra­tory appli­ca­tions to large scale melt­ing oper­a­tions.

Another impor­tant focus of our work is the devel­op­ment and produc­tion of engi­neer­ing ceram­ics, which are reli­ably used in demand­ing tech­ni­cal appli­ca­tions. This includes precisely manu­fac­tured ceramic tubes specif­i­cally designed for use in ther­mally and chem­i­cally highly stressed envi­ron­ments. Mate­ri­als such as aluminum oxide and zirco­nium oxide have proven espe­cially effec­tive. They with­stand high temper­a­tures and impress with their dura­bil­ity and longevity in daily use.

Also remark­able are our zirco­nium oxide ceramic crucibles, which feature outstand­ing mechan­i­cal strength, high chem­i­cal resis­tance, and excel­lent temper­a­ture toler­ance. These prop­er­ties make them ideal solu­tions for appli­ca­tions in labo­ra­tory and medical tech­nol­ogy, as well as in the chem­i­cal indus­try and areas with extreme ther­mal demands

In crys­tal growth, we support our customers with suit­able ceramic compo­nents that meet the high­est require­ments for purity, dimen­sional stabil­ity, and temper­a­ture resis­tance. Our specially devel­oped qual­i­ties help to reli­ably culti­vate sensi­tive crys­tals under controlled condi­tions thus contribut­ing signif­i­cantly to stable processes and consis­tently high prod­uct qual­ity.

Further­more, we supply customers in the fields of invest­ment cast­ing, jewelry cast­ing, labo­ra­tory, and medical tech­nol­ogy with indi­vid­u­ally devel­oped ceramic compo­nents that offer maxi­mum preci­sion and reli­a­bil­ity.

Our motto is: always one step ahead. Through contin­u­ous inno­va­tion, state of the art manu­fac­tur­ing tech­nolo­gies, and close collab­o­ra­tion with research insti­tu­tions, we develop ceramic solu­tions that not only meet today’s require­ments but also define future stan­dards.

Preci­sion cast­ing

The lost-wax cast­ing process is a very old tech­nol­ogy that makes it possi­ble to produce compli­cated indi­vid­ual parts or even large series. Often, the cast­ings do not need to be reworked, thanks to their high preci­sion.

Engi­neer­ing ceram­ics

The diverse prop­er­ties of ceramic prod­ucts offer an immense spec­trum of possi­ble appli­ca­tions. Compo­nents made of ceram­ics can now be found in almost all sectors of the econ­omy.

Illu­mi­nants and the glass indus­try

Illu­mi­nants (lamps and bulbs) are becom­ing ever more effi­cient and energy-saving. Ceramic is used not only as an insu­la­tor but also as a carrier mate­r­ial. It is oxida­tion-free and heat-resis­tant.

Aero­space indus­try

In the aero­space indus­try, the search is on for new mate­ri­als that can meet the exact­ing require­ments. Ceramic is a promis­ing and impor­tant mate­r­ial for this purpose.

Jewellery sector

As in medical and preci­sion cast­ing, jewellery cast­ings are gener­ally produced using the lost-wax cast­ing tech­nique.
