International Syalons at ALUMINIUM 2018 – Düsseldorf

International Syalons will be attending ALUMINIUM 2018 in Düsseldorf , Germany on October 10th – 11th.

The trade fair, which takes place every 2 years, expects to attract more than 27,000 participants to meet with the 1000 exhibitors from 53 countries form around the world. ALUMINIUM is the world’s leading trade show for the aluminium industry and its main applications, and provides an excellent platform to unite producers, processors and end-consumers as well as technology suppliers.

International Syalons has supplied world leading advanced silicon nitride and sialon products to the molten metal handling industry for many years, utilising the outstanding chemical stability of our materials, particularly in contact with non–ferrous molten metals. The exceptional heat and corrosion resistant properties of Syalon ceramics have been utilised in a range of foundry products, including thermocouple protection sheaths, heater and riser tubes, ladles and other foundry products.

The Young’s Modulus of Silicon Nitride Ceramics

Silicon nitride-based ceramics are manufactured to exhibit exceptional thermodynamic properties and compete with conventional refractory materials for resistance to corrosive media and highly fluctuating thermal values. These material properties are associated with enhanced mechanical characteristics, including high strength profiles and outstanding resistance to physical stress.

Thermal Expansion Coefficient of Sialon Ceramics

Technical sialon ceramics are manufactured for refractory applications, providing improved thermodynamic capacities over established industry materials such as alumina (Al2O3) and zirconia (ZrO2). Sialon ceramics are unique for their exceptional balance of thermal and mechanical properties, including superior thermal shock resistance and mechanical integrity under temperatures exceeding 1400°C (2552°F).

Syalon 110: Si3N4 in Ferrous Metal Applications

Sialon ceramics can be thought of as refractory alloys of silicon–aluminum—oxynitride, which have been sintered with an additional oxide stabilizing agent, such as yttria, to form a high-density ceramic that is isostructural with either alpha (α) or beta (β) forms of high-strength silicon nitride (Si3N4). These established refractories exhibit outstanding degrees of physical stability under extreme thermodynamic stress. Composite grades of Si3N4 have been developed to elevate these properties with unique characteristics such as electro-discharge formability and improved corrosion resistant behavior.

The Benefits of Sialon Thermocouple Protection Sheaths

A thermocouple protection sheath is a high-strength insulator designed to protect thermal sensors in extreme temperature conditions. These sheaths are designed as robust cylindrical elements that encapsulate the thermocouple and protect the wiring from process gases, other corrosive media, and mechanical abrasion. A small aperture allows the wiring junction to transmit electronic signals proportional to the temperature values from within an open or closed system, enabling high-stability monitoring of process temperatures in demanding environments such as non-ferrous molten metal handling.

International Syalons Recruit Quality, Health & Safety Engineer

The Board are pleased to announce that, thanks the continued growth of the Company, International Syalons have appointed a new Quality, Health & Safety Engineer. Mark Earle has been with the Company for several months, and is making excellent progress.

Mark has joined the Company with a wealth of quality assurance experience from within the automotive industry, and is looking to transfer his knowledge and introduce additional procedures and working practices to further improve the quality of our products in line with our ISO 9001:2015 accreditation, and ensure the Company maintains its excellent health and safety record.

Oil and Gas Industry: The Benefits of Using Syalons

The depletion of existing hydrocarbon supplies and reserves is well-documented, with the oil and gas industry becoming increasingly circumspect in its attempts to meet a growing demand with a dwindling supply. Petroleum geology and natural gas exploration has transformed in recent years, augmenting traditional prospecting methodologies with new and emerging technologies. Fracking enables oil and gas suppliers to withdraw hydrocarbons dispersed in the strata of the earth’s crust, but this methodology is divisive from an ethical and environmental perspective.
