Preparation of Mesoporous Silicon Carbide from Nano-Sized SiC Particle and Polycarbosilane

Ordered mesoporous silicon carbide (OM-SiC) via polymer precursor nanocasting.

Ordered mesoporous SiC with high specific surface area (650-800 m(2) g(-1)) and well ordered pore structure was obtained via nanocasting of polycarbosilanes into SBA-15 and subsequent conversion of the polymer at 1300 degrees C.

SYNTHESIS OF NANO SIZED MESOPOROUS γ - Al2O3POWDER FROM DOMESTIC HAMEDAN KAOLIN

A method for producing high surface area nano-sized mesoporous alumina from inexpensive Iranian kaolin as raw material is proposed. In this method, first, kaolin was purified for purifying Kaolin, High Grade Magnetic Separation and leaching with HCl and chemical bleaching treatment by using sodium dithionite (Na 2 S 2O4 ) as reducing agent in acidic media (H 2SO 4 ) were used. Pur...

EFFECT OF T6 HEAT TREATMENT ON MECHANICAL PROPERTIES OF CERAMIC REINFORCED CASTED ALUMINUM ALLOY

Aluminium base alloy (Al-Cu-Si) was reinforced with silicon carbide (SiC) particles, in various percentage compositions from 0-20 wt%. Silicon carbide particle size of 20µm was selected. The molten slurry of SiC reinforced base aluminium metal was casted through green and dry sand casting methods and solidification process was carried out under ambient conditions. A selected population...

Chapter 1 Introduction to Silicon Carbide ( Sic ) Microelectromechanical Systems ( Mems )

This chapter serves as a brief introduction to the basic properties of silicon carbide (SiC) and the advantages of using SiC over other semiconductor materials for microelectromechanical systems (MEMS). Given the excellent and extensive review chapters that follow this one, I have confined this chapter to recent research performed at the University of Edinburgh in the area of SiC microelectrome...
