Editorial Policy: Independence, Sources, Request Disclosure and Corrections

This editorial policy sets five rules for RefractoryAdditives.com: one publisher byline, no paid placement, named primary sources with editions and dates, open disclosure of where quote requests go, and a public way to correct errors.

The site covers shaped, monolithic and insulating products, refractory-grade raw materials, binders and additives, properties and tests, and the linings that use them. Every page applies these rules to refractory materials and nothing else.

Every value names its standard and edition, the product data sheet or the dated source it comes from; see our methodology and fact-checking process.

Who Publishes RefractoryAdditives.com and Who Writes It#

RefractoryAdditives.com is published under its own brand, and every article carries the byline RefractoryAdditives.com Editorial Team; no individual author, reviewer or company is named.

Articles are compiled from named primary sources. The site does not claim that an engineer or other expert wrote or reviewed a page, and the byline links to the methodology page.

The editorial team is reached at editorial@refractoryadditives.com. Who stands behind the site is set out under about RefractoryAdditives.com.

Independence From Producers, Suppliers and Contractors#

No producer, supplier or contractor pays to appear on RefractoryAdditives.com, and no company is presented as endorsed or ranked above another. The site earns through supplier quote requests (refractory products, raw materials, additives) and contractor match requests (installation, dry-out, repair), and these requests never change what an article says. Requests go to independent suppliers and contractors, and no company receives them by agreement as of 2026-10-27.

How Companies and Product Names Appear in Articles#

A company appears in an article only as the maker of a named product whose data sheet supplies one typical value, and that value never stands in for a standard requirement.

A producer data sheet describes its own product and never overrides a standard. Market sizes appear only as named analyst estimates with publisher and year, and the site publishes no ranking of producers.

Advertising, Sponsorship and Paid Placement#

The site runs no advertising and loads no analytics or ad vendor scripts. It carries no sponsored article, no paid table row and no paid link, and links to producer pages carry the nofollow attribute.

Sources: Standards, Regulations, Peer-Reviewed Papers and Data Sheets#

Every value on RefractoryAdditives.com comes from a named primary source: a standard with its edition, a regulation with its article or entry and date, a peer-reviewed paper or conference proceedings, or a producer data sheet that describes one named product. Table 1 lists the seven source types, the issuing bodies and the citation form.

Standards come from their issuing bodies: ASTM Committee C08 on Refractories, ISO/TC 33, CEN/TC 187 and API. Links to standards bodies, government and EU sources and peer-reviewed publishers are followed, and every other host is nofollow. The standards the source rule refers to are collected under refractory standards.

Sources the Site Does Not Cite#

Four kinds of source are never cited on RefractoryAdditives.com, whatever they say.

• Wikipedia and other open encyclopedias
• Copies of standards on hosts other than the issuing body
• Snippet-level market estimates without a readable report
• Single online store listings and consumer prices as price data

Prices appear only as dated ranges or quote factors.

How Fact-Checking Shapes Values, Editions and Units#

Each property value carries one of two labels: a standard requirement, named with standard, edition and class, or a typical value of a named product, named with its maker's data sheet.

Three further rules apply. Editions and reapproval years stand on every standard, such as ASTM C27-98(2022), ISO 836:2001 and EN ISO 10059-1:2025, which replaced its EN 993 part on 2025-12-09. Units are metric first with US units in parallel, converted exactly, for example 538 °C (1000 °F) in ASTM C71-12(2024). ASTM and ISO or EN methods are shown side by side and never called equivalent unless the standard says so. A hazard line gives the CLP Annex VI entry where one exists, else the ECHA C&L notified classification, else "see the supplier SDS".

Request Disclosure: Where Supplier and Contractor Requests Go#

A quote or contractor request sent through RefractoryAdditives.com goes to independent suppliers and contractors; no company pays for placement, and the forms ask only for what a quote needs.

The five fields are product or class, quantity, specification, service temperature and country. Forms name no company and promise no price, no response time and no number of replies.

The same wording appears beside every request button on the site:

Form submissions are kept for 24 months from submission; the privacy policy gives the detail. The two request pages are listed below.

• request refractory quotes
• free refractory contractor match

Corrections: How to Report an Error and How It Is Fixed#

To report an error, email editorial@refractoryadditives.com with the page URL, the statement in question and the primary source that contradicts it; a confirmed error is corrected on the page, and the page's reviewed date changes.

A report contains three items.

• Page URL
• Exact statement
• Source: a standard with edition, a regulation with article and date, a paper, or the maker's own data sheet for its own product

A newer official source beats the earlier value, and the page then gives the official value and cites it. Values are rechecked when a standard is reapproved or revised, a CLP adaptation or REACH amendment is published, or OSHA changes a rule. A company request to change a value follows the same rule and needs a primary source.
