Zirconia ceramic,  also known as zirconium dioxide (ZrO2), is a white crystalline oxide of zirconium. Its most naturally occurring form is the mineral baddeleyite with a monoclinic crystalline structure. It has the highest toughness and strength at room temperature of all the advanced ceramic materials. It also has excellent thermal insulation and low thermal conductivity.

Zirconium oxide toughened alumina (ZTA) has mechanical strength and wear resistance and can be used as an ideal material between zirconia and alumina. It was established that ZTA ceramic material is stronger and tougher than regular alumina ceramics.  Typically, ZTA contains 10-20% volume of ZrO2 in alumina. Depending on the percentage of content, the properties of the ceramic can be tailored to suit the application in question. Because of the high price of pure zirconia, ZTA with good toughness is a good choice.

Cerium Boride, also called Cerium Hexaboride or CeB6, is a refractory ceramic material. The principal use of cerium hexaboride is a coating of hot cathodes, or hot cathodes made of cerium hexaboride crystals. It usually operates at temperature of 1450 °C.

Lanthanum Boride, also called Lanthanum Hexaboride or LaB6, is a refractory ceramic material. It has a high melting point of 2210 °C, and is insoluble in water and hydrochloric acid. And it is stable in vacuum. Borides are hard, high-melting materials with metal-like conductivity, and they are stable to nonoxidizing acids but break down in strong oxidizing agents and strong alkalis. Borides are used in semiconductors, superconductors, diamagnetic, paramagnetic, ferromagnetic, anti-ferromagnetic, turbine blades, and rocket nozzles.

Boron Carbide, or B4C, is an extremely hard ceramic material discovered in 1899. The Mohs hardness of boron carbide is about 9.49, ranking the third hardest materials behind diamond and cubic boron nitride. It was applied widely in industries as wearing resistant material, abrasive.
