Кафедра "Технологія кераміки, вогнетривів, скла та емалей", первісна назва – кафедра силікатів, була створена в 1926 році в складі Харківського Хіміко-технологічного інституту.

Першим завідувачем кафедри (1926 – 1941 рр.) та засновником наукової школи був вчений зі світовим ім'ям, тричі Лауреат Державних премій, Заслужений діяч науки і техніки, академік АН УССР і член-кореспондент АН СССР, доктор технічних наук, професор Петро Петрович Будніков. Підготовка спеціалістів з силікатних технологій була започаткована в 1910 році на кафедрі мінеральної сировини під керівництвом академіка Єгора Івановича Орлова.

Кафедра входить до складу Навчально-наукового інституту хімічних технологій та інженерії Національного технічного університету "Харківський політехнічний інститут".

У складі науково-педагогічного колективу кафедри працюють: 5 докторів та 3 кандидата технічних наук; 4 співробітника мають звання професора, 3 – доцента.

    Oxidation-resistant nano-reinforced PC-refractories of modified phenol formaldehyde resin. Part 3. Formation mechanism of organic-inorganic complexes during low-temperature synthesis of nanoparticles of additional antioxidants and their effectiveness
    (Kluwer Academic/Plenum Publishers, USA, 2017) Semchenko, G. D.; Shuteeva, I. Yu.; Povshuk, V. V.; Rozhko, I. N.; Borisenko, O. N.; Angolenko, L. A.; Starolat, E. E.; Shmygarev, Yu. M.; Vasyuk, O. A.
    SiC nanoparticles that could be used as an antioxidant for periclase-carbon (PC) refractories were synthesized from the organic—inorganic complex (‒СН₃)‒(SiO₂)n that formed during heating of silicon alkoxide and thermal destruction of its gels. Use of phenolformaldehyde resins modified with silicon alkoxide and its sols was proposed and enabled the formation of an organic—inorganic complex (-СН₃)‒(SiO₂)n‒С with a high C content. This increased the yield of SiC synthesized in the carbon binder. The addition of Ni precursors (additional antioxidant) formed an even more complicated organic—inorganic complex. Use of the complex (‒СН₃)‒(SiO₂)n‒Ni(NiO)‒С together with Al improved the operating characteristics of the PC refractories. It was found that their resistance to oxidation was increased after the complex antioxidant Al + SiC + Ni(NiO) formed.

    Oxidation resistance of nano-reinforced PC-refractories modified with phenol formaldehyde resin. Part 4. Thermodynamic evaluation of phase formation within Mg–O–C–Al, Mg–O–C–Ni and МgO‒Al₂O₃‒NiO‒SiO₂ systems using SiC + Al + Ni (NiO) complex antioxidant
    (Kluwer Academic/Plenum Publishers, USA, 2017) Semchenko, G. D.; Borisenko, O. N.; Brazhnik, D. A.; Logvinkov, S. M.; Povshuk, V. V.; Shuteeva, I. Yu.; Angolenko, L. A.; Chopenko, N. S.; Vasyuk, P. A.
    Results are given for the synthesis and co-existence of phases formed from components of complex organic- inorganic antioxidant formed during modification of phenol-formaldehyde resin (PFR) and graphite with silica alkoxide and inorganic or organic nickel precursors. Thermodynamic analysis is given for the Mg–Al–C and Mg–O–Ni–C systems. It is shown that the periclase and carbon can coexist with aluminum and nickel, and also that oxidized antioxidants Al₂O₃ and NiO can interact respectively with the periclase and with the synthesized SiC formed during modification of PFR with silica. In considering the NiO‒MgO‒Al₂O₃‒SiO₂ system it is established that during service noble spinel will be synthesized from the complex antioxidant components, facilitating an increase in PC-refractory durability in service.

    Features of high-strength composite material structure creation
    (Kluwer Academic/Plenum Publishers, USA, 2015) Semchenko, G. D.; Makarenko, V. V.; Logvinkov, S. M.; Shuteeva, I. Yu.; Katyukha, A. S.
    The basis of technology proposed is use of a sol-gel method for preventing polycrystalline corundum fiber from crystallization during heating to high temperature and for low-temperature synthesis of prescribed phases in a corundum matrix with the aim of improving the operating properties of composite materials based on corundum. As a result of firing a charge based on corundum powder modified with tetraethoxysilane and polycrystalline corundum fiber modified with ethylsilicate-32 at 1360°C materials are created with very good strength properties. The materials exhibit electrical insulation properties and are stable in ionized gas streams at the level of known analogs as a result of creating self-reinforced mullite and β-SiC corundum matrix, reinforced with polycrystalline fiber and rapidly sintered due to presence of silicon oxynitride.

    Formation of material prescribed phase composition from refractory filler silica powder modified with alkoxide and sol-gel composite
    (Kluwer Academic/Plenum Publishers, USA, 2014) Semchenko, G. D.; Shuteeva, I. Yu.; Ryshchenko, M. I.; Borisenko, O. N.
    Creation of ceramics and refractories with improved physicomechanical properties is possible with use of nanomaterials in their technology. Introduction of SiC nanoparticles into a ceramic material charge by using modified filler powders is proposed. Fillers modified with tetraethoxysilane during grinding leads to powder crystal structure breakdown and SiC mechanochemical synthesis. The amount of -SiC synthesized in this way depends on the amount of modifying additive. Results are provided for modified filler phase composition before and after heat treatment at 1000°C, and mechanochemically synthesized SiC thermal stability is established. It is shown that sintering of modified electro-corundum worsens with an increase in amount of synthesized silicon carbide nanoparticles. The difference is demonstrated in phase composition formation with heat treatment of a mixture of modified and normal finely ground electrocorundum with a sol-gel binder and firing up to 1600°C. Silicon carbide nanoparticle synthesis does not exceed 3 – 7 % in both cases. Recommendations are given for use of corundum filler with a different amount of modifying additive.

    Synthesis of β-SiC in the intermediate layer of corundum coatings based on a sol-gel binder for protecting graphite objects from oxidation
    (Kluwer Academic/Plenum Publishers, USA, 2011) Semchenko, G. D.; Shuteeva, I. Yu.; Ryshchenko, M. I.; Panasenko, M. A.; Ryabkov, Yu. I.
    A coating is developed for protecting graphite from oxidation at 2023 – 2223 K. The efficiency of the protective action of a corundum coating based on a sol-gel binder increases due to creating a dense intermediate layer between the graphite substrate and the coating as a result of its self-reinforcement with fibers of mullite crystals and -SiC nanoparticles. Components of a modifier and sol-gel binder, but not carbon of the graphite substrate, provide synthesis of β-SiC.
