Abstract— Nowadays, ceramic matrix composites are being extensively used for industries and household purposes. However, these ceramic composites materials are substantially resistant to biodegradation. In this experimental study the specimen of silicon carbide with varying percentage of titanium carbide (TiC) has been fabricated by using microwave sintering. Different samples having TiC 5%, 10%, 15% (wt%) were prepared by die pressing. Then sample were heated in microwave furnace at different range of temperatures i.e. 1150°C, 1250°C and 1350°. It was found that with increase in the weight percentage (wt %) of TiC, the porosity was maximum in 1150°C and minimum porosity achieved maximum temperature 1350°C. The maximum hardness was achieved in 1350°C when 15 wt % of TiC. Density was also increased with respect to the increase in temperature and TiC wt %.

Ceramic matrix composite (CMC's) were developed to overcome essential brittleness and many reliability of massive and uniform ceramic, with a view to introduce ceramic in structural part used in various environments, such as rocket and jet engines, gas turbines for power plants, heat shield for space vehicles etc[3,8]. It is generally admitted that the use of CMS's in advanced engine can be operated and eventually the elimination of the cooling fluids, both resulting in an increase of yield. There is a wide spectrum of CMS's depending on the chemical composition of the matrix and reinforcement [12]. Non-oxide CMS's are by far those which have been the most studied [11]. Among the various non-oxide ceramics that found commercial applications, silicon carbide (SiC) is the leader. Silicon Carbide is the main concoction compound of carbon and silicon. Attractive properties, such as good specific strength and Young’s modulus as a function of temperature, the specific stiffness, corrosion and erosion resistance made SiC an attractive alternative to the hard metal compositions [7]. SiC has turned a special attention as advanced ceramic material recently since it offers superior properties such as high hardness, low bulk density, high oxidation resistance, thermal conductivity and thermal shock resistance [9]. Furthermore, it is an important ceramic used in structural applications, such as automotive engines, cutting tools, heat exchange and mechanical seals [2,10]. Additionally, it is used in bulk form as refractory products, as electric heating elements and resistors, as igniters for gas appliances, as ceramic burners, as mechanical seal faces, as radiation sensors, as low-weight high-strength mirrors, as high power and high temperature semiconductor devices, as radiation resistant semiconductors and as light-weight armors [2, 13]. Silicon Carbide is the base material another material is Titanium Carbide Titanium carbide is a to a great degree hard obstinate earthenware material, like tungsten carbide. This experiment using two additives yttrium oxide and aluminum oxide both have great heat conductivity.PVA is a colorless, water-soluble synthetic resin employed principally in the treating of powder. For making pellets in laboratory scale processing normally we make 25 % PVA solution in distilled water (2.5gm PVA in 98 ml water).
